        * source/cmt_generators.cxx (build): Add an option -no_stamps to
        buid dependencies so as to generate a version of the dependency
        files without the extra stamps specifications and with no stamp
        file generation. This is need to generate the bootstrap dependency
        file for cmt itself.

        * source/cmt_generators.h (class DependencyGenerator): 
        * source/cmt_generator.h (class CmtGenerator): Revisit the construction of dependencies files:

        * src/cmt_install_area.cxx (instance): The constuction of the
        instance also declares the path patterns.

        (setup): Make use of the path_patterns to generate CMT statements

        (get_install_area): The current install area is preserved in the
        InstallAreaMgr instance (singleton).

          if not erase the corresponding installed file.

        * src/cmt_install_area.h (class CmtInstallPathPattern): New class
        for storing generic patterns for (PATH/directories) duets
        generation and management inside install area mechanisms.  The
        point is to describe special conventions for things to be
        installed within the installation area.

        We describe that in terms of a set of :
        
           o path-like variable names
           o subdirectory patterns bellow $CMTINSTALLAREA

        All those patterns will be used to configure the installation area
        and to expand the specified PATH-like variables.

           Ex: 
              PATH            is associated with ${CMTCONFIG}/bin
              LD_LIBRARY_PATH is associated with ${CMTCONFIG}/lib
              CLASSPATH       is associated with share/bin

           we could think of having those patterns defined in the
           requirements file.

        * src\cmt_use.cxx (show_sub_uses): Ensure that the cmt show uses
        displays the correct scoping information for uses and
        sub-uses. cmt show uses also displays the full tree even when it
        contains private uses.

2002-01-30    <arnault@lal.in2p3.fr> 68

        * src/cmt_parser.cxx (parse_arguments): Fix the bug of private
        environment variables which could not be set even within the
        package (bug in the management of the -pack= -version= -path=
        options).

        * src/cmt.h : Install all attributes of the Cmt class as private
        attributes, and make them follow the convention : m_xxx. This
        implies to install few accessor methods.

2002-01-29    <arnault@lal.in2p3.fr> 67

        * src/cmt_use.cxx (class use_action_iterator): The private uses

            - show uses operations

        * src/cmt_symbol.cxx (action): Expands the specified script name

2002-01-11  Christian Arnault  <carnault@lxplus035.cern.ch> parallelbuilds

        * src/Makefile.header: Reorganize basic Makefile fragment
        generation to permit better support for parallel & concurrent
        builds.  Mimize also the number of makefile fragments generated
        and kept : only $(tag).make remains in ../cmt . All other are
        thrown away after use.

        Make those changes a branch "parallelbuilds"

        * src/Makefile.header (tags): Attempt to fix the continuity break
        between v1r9 and v1r10, by re-installing the possibility to use
        gmake tag=<...> rather than having to use source setup.[c]sh
        -tag=<...>

        (This fix has to be tested before any validation)

2001-11-26  Christian Arnault  <carnault@atlas50.cern.ch> 64

        * Tagging v1r10p20011126
        
        * src/Makefile.header: tag is now ${CMTCONFIG} and tags ${CMTEXTRATAGS}

        * mgr/requirements: Provide the macro tags as ${CMTEXTRATAGS}

        * src/cmt_tag.cxx: Various changes in strategy for tags:
          - tag inclusion (defined by the "tag" statement) transmits the priority.
          - tag selection can be discarded by exclusion specifications. Exclusion 
          qualifies a set of contradictory tags. Contradictory tags will be selected
          according to their priority or to their declaration order in case of
          equal priority.

        * src/cmt_parser.h (enum Priority): Change the priority list:
        Arguments get highest priority
        then CMTCONFIG
        then user tags (those defined in requirements)

        * fragments/make_setup: produce uses.make and tags.make

        * src/cmt_parser.cxx (parse_arguments): 
        * src/cmt.h (class Cmt): Suppress the mechanism of

        consider previous setenv settings.

        * src/cmt_generator.cxx (build_dependencies): Using ../$(tag) for
        output base of the dependencies fragment rather then
        Cmt::current_tag

        * src/Makefile.header (CMTPRIMARYTAG): tag=... argument of gmake
        will override CMTPRIMARYTAG. However internal tag macro is only
        replaced with ${CMTCONFIG}

        * fragments/make_setup (config): create a tags.log (for cmt show
        tags)

        * mgr/cmt_make_shlib_common.sh: Add the ${lib} prefix to the
        temporary expansion directory. Fix a bug in sed filter for all
        module files.

        absence of CMTPRIMARYTAG

        * src/cmt_system.cxx (create_symlink):

        * src/cmt_tag.cxx (is_selected): Change the Tag::selected attribute to bool.

2001-11-07  Christian Arnault  <carnault@lxplus006.cern.ch> 60

        * src/cmt_symbol.cxx (build): Implement the possibilty to have
        reflexive asignment to symbols: when a symbol value is exactly
        specified (from set, macro or path statements) using $(<name>) or
        ${<name>} or %<name>% then the old value is preserved for all
        corresponding selectors.

        * src/cmt_parser.cxx (set_standard_macros): Re-activate -import
        options (that had been discarded!)

        * src/cmt_use.cxx (add): Generate an error when a package is not
        found (the error was only generated at "cmt show uses")

        * src/cmt_constituent.cxx (show): Display -import options

        build_library_links

        * src/cmt_parser.cxx (restore_all_tags): Get the value of
        CMTPRIMARYTAG to configure Cmt::primary_tag.

        Leave unchanged the primary_tag and the extra_tags except if
        overridden through the -tagxxx= options

        * src/cmt_parser.h (enum): Add PrioritySite in the list of
        possible priorities.

        * src/cmt.h (class Cmt): Add the restore_all_tags function. Add
        the extra_tags attribute . Change the strategy of tag persistency:

          o CMTPRIMARYTAG always contains what had been specified using
        the -tag= option,

          o CMTEXTRATAGS contains what had been manipulated by -tag_add=
        and -tag_remove= options.

          o CMTCONFIG is setup independently of the primary tag.

        * src/Makefile.header (primary_tag): Propagate tags using
        CMTPRIMARYTAG instead of CMTCONFIG (except when CMTPRIMARYtAG is
        not yet defined)

        * src/cmt_constituent.cxx (parse): Fix the word parsing for
        constituent specification...

        * src/cmt.h (class Cmt): Adding support of CMTHOME environment
        variable for specifying home requirements file. Default value will
        be ${HOME}. And can be overridden through the -home=<directory>

        * src/cmt_parser.cxx (use_home_requirements): Add the systematic
        search for a requirements file located in ${HOME}. This
        requirements file when found, is systematically parsed AFTER the
        requirements file of the current package has been parsed (so as to
        give the highest precedence to its statements)
        
        (do_remove_library_links): Upgrade "remove library_links" to make
        it compliant to the algorithm used in "build library_links"

        removed.

        * src/setup.zsh: upgrade the completion for the broadcast command.

        * src/cmt_parser.cxx (do_broadcast): Make the -select independent
        of the -local or -global options. This is achieved by adding a
        "path_selections" list only managed by the -depth, -local -global
        modifiers while the "selections" list is managed by the -select
        modifier. The -exclude is left unchanged.

2001-08-22  Christian Arnault  <carnault@lxplus024.cern.ch> 36

        * src/cmt_cvs.cxx (class CvsImplementation): Add the possibility
        to transmit a flag to the CVS pluggin, by inserting a /cmtcvstest
        in the module name to import. This will have to be decoded by the
        CVS pluggin itself !!

2001-08-21  Christian Arnault  <carnault@lxplus013.cern.ch> 35

        * src/setup.tcsh: Improving the tcsh completion mechanism (for cmt co).

        * src/setup.zsh: Improving the zsh completion mechanism (for cmt co).

        * src/cmt_cvs.cxx (class CvsImplementation): Converging on HEAD
        management strategy...

        Starting implementation of the Atlas filter for CVS tags right
        into cmt_cvs.cxx rather than inside the CVS pluggin...

2001-08-20  Christian Arnault  <carnault@lxplus028.cern.ch> 34

        * src/cmt_cvs.cxx (class CvsImplementation): Improving the
        recursive checkout process

2001-08-20    <arnault@lal.in2p3.fr> 33

        * src\cmt_cvs.cxx (class CvsImplementation): Reorganizing some CVS operations:<ul>
          <li> Apply the CMTCVSOFFSET env. variable to all actions (tags, branches, subpackages)
          <li> cleanup checkout algorithms (remove some obsolete variables)
          <li> add the -requirements <requirements-file-path> option to checkout according to
            a set of use statements.
          <li> remove the inheritance to Awk of CvsImplementation to split the filter into 2
            phases (implemented as 2 separated Awk derived classes) RecursivePass1 and
            RecursivePass2.</ul>

2001-08-16  Christian Arnault  <carnault@lxplus046.cern.ch> 32

        anymore when CVSROOT is set to kserver!!!!

2001-07-16  Christian Arnault  <carnault@lxplus030.cern.ch> 28

        * doc/CMTDoc.html: Old PREFIX fragment variable has been replaced
        by FILEPATH long ago. This was not upgraded in the doc.

        * fragments/constituent: The -f <file> MUST be specified BEFORE
        other Make flags!!

        * fragments/dependencies: Tried to comment out the dependencies to
        cmt_path.make etc... but it confused the dependencies fragment
        production. Uncomment it but need to understand the side effect.

2001-07-09  Christian Arnault  <carnault@lxplus012.cern.ch> 27

        * src/cmt_generator.cxx (build_readme): Bug: the VERSION variable

        * fragments/dependencies: Cleaning some old debug printouts.

        * src/cmt_cvs.cxx (class CvsImplementation): Bug in replacing the
        wild card expression. v5r* has to be replaced by v5r0 while v5*
        has to be replaced by v5 in case no matching tag exists in the CVS
        repository.  Other bug : All split operations should be performed
        against " \t" (include tab character)

2001-06-29  Christian Arnault  <carnault@lxplus047.cern.ch> 24

        * src/cmt_cvs.cxx (class CvsImplementation): Final Validation of
        the change in the implementation of the m_installed stack used to
        avoid recursion due to dependency cycles.

2001-06-22  Christian Arnault  <carnault@lxplus020.cern.ch> 23

        * src/cmt_cvs.cxx (class CvsImplementation): doing some
        optimizations for the big checkout operations.

        * src/cmt_parser.cxx (do_config): Remove .[n]make files also from
        the binary directory.

        * src/cmt_cvs.cxx (class CvsImplementation): Always fetch the cmt
        branch at HEAD even if the checkout operation is applied to a
        required tag (temporary feature).

        * src\cmt_cvs.cxx (class CvsImplementation): insert a space
        between top tags and other tags.

        * mgr\cmt_make_shlib.bat: Write extra options received through
        arguments into a temporary option file, used by @<optionfile> to
        resolve line-too-long prolems.

        * fragments\nmake\cpp_library: 
        * fragments\nmake\cpp:
        Add the /Tp qualifier for allowing non-standard file suffixes.

2001-06-05  Christian Arnault  <arnault@lal.in2p3.fr> 22

        * src/cmt_use.cxx (class use_action_iterator): Default to the
        -no_auto_import was to keep the most recent specification. Change
        this to always request auto_import by default, (unless otherwise
        specified)

2001-06-01  Christian Arnault  <arnault@lal.in2p3.fr> 22

        * src/cmt_parser.cxx (do_broadcast): Bug fix in do_broadcast: the
        -begin option wrongly implied the -global option.

2001-06-13    <arnault@lal.in2p3.fr> 22

        * src/cmt_cvs.cxx (class CvsImplementation): Improving the
        strategy for getting version tags from the repository:
          o If a request specifies a tag which is not applied to the 
            requirements file, the specified tag is used to create the
            version directory but the HEAD is used in the repository.
          o CvsImplementation::show_cvs_infos () :
            stores all received infos into xxx_info corresponding
            local properties. Thus this method is only called once per
            package.
          o Error messages are really obtained from the error_info field.

2001-05-30  Christian Arnault  <arnault@lal.in2p3.fr> 22

        * src/cmt_generator.cxx (build_document_makefile):
        * src/cmt_system.cxx (get_dot_suffix): fix bug for file_names
        without any suffix

        * src/cmt.h & src/cmt_parser.cxx (set_standard_macros): Add a
        state standard_macros_done to protect against multiple calls to
        set_standard_macros.

2001-05-28  Christian Arnault  <arnault@lal.in2p3.fr> 22

        * src/cmt_cvs.cxx (class CvsImplementation): display the tags in a
        one-per-line basis instead of space separated when doing cmt
        cvstags.

        * src/cmt_use.cxx (operate): Make the version selector operator a
        little bit more quiet...

2001-05-25  Christian Arnault  <arnault@lal.in2p3.fr> 22

        * mgr/Makefile (demo): improve the gmake check action in the demo
        target.

        Improve some error messages.

2001-05-21    <arnault@lal.in2p3.fr> 21

        * src\setup.bat: Improved skeleton for setup.bat. Base it on
        CMTBIN rather than on CMTCONFIG. Do not override CMTCONFIG if
        defined by the user. Do not care about PATH for Visual tools.

        * mgr\install.mak: change the strategy for building the setup.bat
        script for CMT itself at INSTALL time. Now copy ..\src\setup.bat
        skeleton.

        * mgr\requirements: Fix WIN32/VisualC tag definitions and PATH
        settings for cleaner handling of default tag overriding.

        * src\cmt_use.cxx (operate): Implement the algorithm for using
        aliases to alternate version specification in uses.

        policies.

        * src/cmt_cvs.cxx (class CvsImplementation): Adding the -o offset
        option to cmt checkout for specifying a global offset to the base
        CVS repository. This offset will be prepended to all modules
        during the various CVS operations.

        the m_offset attribute is added to the CvsImplementation class.

        (class CvsImplementation): Improve protection against CVS modules
        not found.
        
        (class CvsImplementation): Added the --help option the cmt checkout.

        * fragments/dependencies: take the improvements into account.

        * src/cmt_generator.cxx (build_dependencies): Improve the
        dependency builder: re-generate all entries of the
        <constituent>_dependencies.make that are missing from the complete
        source list (thus regenerate it when it is empty).
        Optimize the file scan for getting the new source list.

        * src/cmt_parser.cxx (do_build_dependencies): Dynamically shifts
        arguments of the build dependencies command to keep only the
        new-source-list. The complete command being 
        "cmt <args> build dependencies <constituent-name> <new-source-list>"
        
        (do_config): drop all makefile fragments from the mgr/cmt
        directory AND from the binary directory.

2001-05-11  Christian Arnault  <arnault@lal.in2p3.fr> 19

        * src/cmt_deps_builder.cxx (): Augmented local internal
        line buffer (from 1024 to 16384).

        * doc/CMTDoc.html: document the new &lt;package>_root macro

        * src/cmt_parser.cxx (set_standard_macros) (get_best_form): Define
        a new set of standard macros using the pattern <package>_root
        similar to <PACKAGE>ROOT except that this new definition uses the
        get_best_form, with a relative path to the package. The
        <PACKAGE>ROOT macro is restored to the previous convention, that
        it uses the absolute path.
        
        * src/cmt_use.cxx (fill_includes_macro): Adapt the
        fill_includes_macro to use the new <package>_root standard macro


2001-05-10  Christian Arnault  <arnault@lal.in2p3.fr> 18

        * src/cmt_parser.cxx (do_broadcast): Add the -begin=<pattern>
        option to start the broadcast loop from a given package. This
        option can be combined with other options such as -select or
        -exclude.

        * src/cmt_generator.cxx (filter_paths): Suppress two unused
        variables.

        * src/cmt_use.cxx (add): Bug fixing: during the discovery of
        versions requested for a given package, the discarded versions
        were not correctly replaced by the finally selected version,
        especially in the Use::get_paths method. The
        Use::get_selected_version has been added to obtain the effective
        replacement for a discarded version.

        * fragments/check_application: suppress the ". setup.sh" before
        application run.

2001-05-04  Christian Arnault  <carnault@lxplus023.cern.ch> 17

        * src/cmt_parser.cxx (set_standard_macros): The production of all
        use_xxx standard macros now is based on a "macro_append" keyword
        instead of "macro", since "macro" resets all previous
        definitions. Therefore if the user's requirements did augment
        those use_xxx macros, these specifications would be ignored.
        
        (do_broadcast): Set the -local option to broadcast the
        default. Add the -global option to revert to the old default (with
        no selection and to any depth)

2001-05-03  Christian Arnault  <carnault@lxplus019.cern.ch> 17

        * src/cmt_symbol.cxx (add_value_to_list): A new macro or set
        keyword resets (discards) all previous definitions for the
        corresponding symbol.

        * src/cmt_symbol.h (class SymbolValueList): Added an attribute
        discarded for symbol resetting.

        * src/cmt_parser.cxx (print_macros): Exclude scripts from macros
        defined in the $(tag).make file.

2001-04-27  Christian Arnault  <carnault@lxplus022.cern.ch> 16

        * src/cmt_parser.cxx (get_best_form): Validate the compression
        algorithm for paths to packages (only for the macro <PACKAGE>ROOT
        - this is still not true for the <PACKAGE>ROOT environment
        variable) into a relative form when it is shorter than the
        absolute form.

        * src/cmt_system.cxx (compress_path): Fix the algorithm for
        compressing the patterns "aaaa/xxxx/../bbbb" into aaaa/bbbb.

        * src/cmt_generator.cxx (filter_paths): use
        CmtSystem::compress_path instead of duplicating its algorithm for
        erasing "/aaa/.." patterns

2001-04-25  Christian Arnault  <carnault@lxplus022.cern.ch> 15

        * src/cmt_parser.cxx (set_standard_macros): Prepare the production
        of <PACKAGE>ROOT macros as relative paths rather than absolute
        ones, when the relative expression is shorter than the absolute
        one. Temporarily, trigger that feature by setting the
        CMTTESTPREFIX environment variable until absence of side effects
        is confirmed.

2001-04-18  Christian Arnault  <carnault@atlas009.cern.ch> 15

        * src/cmt_generator.cxx (build_readme): bug when generating the
        readme_trailer fragment : the PACKAGE variable should be reset to
        current.

2001-04-11  Christian Arnault  <arnault@lal.in2p3.fr> 15

        * src/cmt_generator.h (class Generator): 
        * src/cmt_parser.cxx (do_build_readme): 
        * src/cmt.h (class Cmt): do_build_readme now propagates argument list

        * fragments/readme_trailer:
        * src/cmt_generator.cxx (build_readme): Added DATE and USER information when building the README.html file. readme_trailer fragment updated accordingly.
        
        (build_readme): Add the -url=<url> argument to the cmt build
        readme command. The specified URL will be used in place of the
        package path when generating the URL for used packages.

2001-04-18  Christian Arnault  <arnault@lal.in2p3.fr> 14

        * src/cmt_symbol.cxx (build): In all builder objects, symbol value
        lists registered by discarded Uses are now ignored.

        * src/cmt_symbol.h (class SymbolValue): cleanup a comment.

        * src/cmt_symbol.cxx (print): protect setup script execution
        against missing files.

2001-04-10  Christian Arnault  <arnault@lal.in2p3.fr> 13

        * src/cmt_generator.cxx (build_readme): 
        * fragments/readme_use: building readme.html requires to know the
        mgr/cmt style of each used package. This fragment now requires a
        fourth variable MGRSTYLE which reflects the use->mgr_style
        attribute. Generator::build_readme fills in this new variable.

2001-04-06  Christian Arnault  <arnault@lal.in2p3.fr> 12

        * src/cmt_parser.cxx 
        (reach_current_package): Use CmtSystem::getenv instead of base getenv
        
        * src/cmt_symbol.cxx (action): Now really private stuff is
        selected when access is at UserMode and scope is Private.

        * src/cmt_use.cxx (add): This method does not need to maintain
        current scope and access mode any longer.

        * src/cmt_parser.cxx (parse_requirements): Cmt::parse_requirements
        now manages the AccessMode and Scope when recursing into
        requirements files of used packages.

        Cmt::scope          handles the sticky state provided by private/public statements
        Cmt::current_access handles the access mode that reflects the situation of the user

        * src/cmt_parser.h (enum): introduce the AccessMode to distinguish
        between DeveloperMode (when pwd is in the current package
        directory) and UserMode (otherwise).

        * src/cmt.h (class Cmt): Cmt::current_mode is now current_access
        and is of type AccessMode

        * src/cmt_parser.cxx (reach_current_package): Use
        CmtSystem::getenv instead of base getenv

        * src/cmt_use.cxx (Use::get_paths): 
        * src/cmt_pattern.cxx (Pattern::apply ()) : bug in computing the
        path between two Uses. The result now includes the current Use.

2001-04-05    <arnault@lal.in2p3.fr> 12

        * src\cmt_tag.cxx (Tag::add(const cmt_string& name, int priority):
        clear a newly created Tag object (to deal with the reuse of old
        objects)

        * src\cmt_pattern.cxx (Pattern::add) : clear a newly created
        pattern object (to deal with the reuse of old objects)

        * src\cmt_use.h (class Use): Add Use::author_action and
        Use::manager_action to fill in the author and manager information.

        * src\cmt_parser.cxx (select): fill in author and manager values
        with the complete line. When several author and manager statements
        are provided, fill in as several lines (separated with a new-line).

        * src\cmt_generator.cxx (analyze_file (const Constituent&
        constituent, const cmt_string& file) : production of objects for
        libraries and applications is strictly identical.

2001-04-03  Christian Arnault  <arnault@lal.in2p3.fr> 11

        * src/cmt_constituent.cxx (clear): constituent.parameters was not
        cleared in Constituent::clear

        * src/cmt_symbol.cxx (build): add cleanup ValueList objects after
        their addition for ensuring a really new value (due to cmt_string
        optimizing)

2001-04-03  Christian Arnault  <carnault@atlas006.cern.ch> 10

        * mgr/Makefile: Operate the demo targets on different make action
        lines

        * src/Makefile.header: Added -tag=$(tag) to cmt actions

        * fragments/generator_header: create the output directory if
        needed

2001-04-02    <arnault@lal.in2p3.fr> 9

        * fragments\nmake\constituent: added the -tag=$(tag) option to cmt
        build actions

        * src\cmt_parser.cxx (parser): show_constituentxxx recursively
        reads used requirements files

        * src\cmt_pattern.cxx (Pattern::apply () const): protection added
        for the case where the pattern is applied to the package that
        defines it.

2001-03-29  Christian Arnault  <carnault@atlas005.cern.ch> 8

        * src/cmt_use.cxx (get_paths): 
        * src/cmt_use.h (class Use): 
        * src/cmt_pattern.h (class IgnorePattern): 
        * src/cmt_pattern.cxx (const apply): Bug in apply global patterns
        : a pattern defined in one package should only be applied to the
        Uses that are on one of the paths between the current Use and the
        one wher the pattern is defined (and not to the Uses that never
        pretend to inherit that pattern!!!)

        This required to implement the Use::get_paths which fills in the
        inclusive list of all Uses that are between two Uses.

2001-03-27  Christian Arnault  <carnault@lxplus017.cern.ch> 7

        * fragments/dependencies: protection against missing dependency
        make fragment during clean operations.

        * src/cmt_constituent.cxx (class constituents_action_iterator):
        the -suffix= option was hidden by the user variable specification
        while parsing the constituent parameters.

2001-03-23  Christian Arnault  <carnault@atlas007.cern.ch> 6

        * mgr/requirements: clean up WIN32 tag variants definitions

        * src/Makefile.header (setup.make): Display of the target in case
        of target not found (.DEFAULT)

        * fragments/make_setup (csh): few checks

        * fragments/installer: add the creation of $(install_dir) if
        needed

2001-03-21  Christian Arnault  <arnault@lal.in2p3.fr> 5

        * src/cmt_parser.cxx (parse_arguments): When the tag specified in
        the command line arguments (using -tag=<tag>) is the same as
        CMTCONFIG, then still validate the tag given by uname

        * fragments/dependencies: generate
        ${CONSTITUENT}_dependencies.make into $(bin)

        * fragments/constituent: generate ${CONSTITUENT}.make into $(bin)

        * src/cmt_constituent.cxx (parse): 
        * src/cmt_constituent.h (class Constituent): Added the two-step
        parsing of the constituents specifications : first stage during
        parsing of the requirements file, parameters are simply stored in
        the constituent object and not interpreted. Second stage : after
        building the standard macros (once requirements files have
        entirely been read) then constituent objects are parsed.

        * src/cmt_parser.cxx: Add Constituent::parse_all in
        Cmt::set_standard_macros to finalize the constituent
        parsing. Install set_standard_macros in several additional actions



2001-03-16  Christian Arnault  <arnault@lal.in2p3.fr> 4

        * src/cmt_cvs.cxx (class CvsImplementation): Get the files at the
        top directory when doing a cmt checkout.  

        Only checkout at head for the top package (ie do not recurse at
        head) and when -r is not specified.

        * src/cmt_symbol.cxx (resolve_value_for_macros): Perform the
        substitution of ${} to %% (or reverse) even if the env. var. is
        not defined in CMT.

        * src/cmt_parser.cxx (install_setup_scripts): Setup scripts on
        Windows generate the temporary expansion script in
        %HOMEDRIVE%%HOMEPATH%.

2001-03-16  Christian Arnault  <carnault@atlas009.cern.ch> 3

        * mgr/requirements: clean up variants for VisualC and
        VisualC/debug

2001-03-15    <arnault@lal.in2p3.fr> 2

        * src\cmt_use.cxx (class use_action_iterator): Strange name
        conflict: the use_action_iterator::set method is in conflict with
        something else when the class is named "action_iterator" (is it a
        conflict with the same private class defined in Symbol.cxx ??)

        * src\NMakefile.header (cmtexe): Fix for re-building cmt when
        cmt.exe does not exist.

2001-03-13  Christian Arnault  <arnault@lal.in2p3.fr> 1

        * src/cmt_use.cxx (class action_iterator): Introducing the
        action_iterator class for managing the local expansion of macros
        in the syntax parser (similart to what was done in Symbol::action)

        * src/cmt_generator.cxx (Generator::build_make_setup) when
        generating setup.make, the default value for constituents is
        extracted from the constituents macro.

2001-03-06  Christian Arnault  <arnault@lal.in2p3.fr>

        * src/cmt_cvs.cxx (class CvsImplementation): Show both top tags
        and non-top tags in cmt cvstags.

        * doc/CMT.htm: Addition of several slide shows (from Atlas)

        * mgr/cmt_buildcvsinfos2.sh (error): The awk script had to be
        protected against multiple ocurrences of the /symbols/,/locks/
        pattern.

        Implement both in python and in shell script the differntiated
        production of top tags and non-top tags. Top tags are the set of
        tags sharing the most recent CVS tagged version id (ie. the HEAD
        may be more recent)

2001-03-05    <arnault@lal.in2p3.fr>

        * src\cmt_parser.cxx (do_build_library_links): Handle libraries
        specified as a full path in <package>_libraries

        * src\cmt_parser.cxx (print_context): 
        * src\cmt_symbol.cxx (all_print): Use one line per
        env. var. assignment when generating setup scripts (instead of ;
        separated instructions) . The latter style should be no longer
        needed since we use temporary files.

        * src\cmt_parser.cxx (set_standard_macros): Add CMTCONFIG to the
        standard sets, so as to let it known as a plain "symbol"

2001-03-02    <arnault@lal.in2p3.fr>

        * src\cmt_system.h: introduce the CmtSystem::ev_open () and
        CmtSystem::ev_close () to get the OS-dependent pattern for
        environment variable definition.

        * src\cmt_symbol.cxx (resolve_value_for_macros): Substitute
        patterns ${xxx} or %xxx% to the appropriate OS-dependent pattern
        when producing "set" values only (this is only done when the
        pattern is not already the good one)

        * src\cmt_parser.cxx (install_setup_scripts): Changed
        >>${tempfile} into >${tempfile} in setup scripts (fix a constraint
        in csh)

2001-02-26  Christian Arnault  <arnault@lal.in2p3.fr>

        * src/cmt_parser.cxx (do_build_temporary_name): Add the build
        temporary_name command to supply that missing function on various
        shells.
        (install_test_setup_scripts): Apply this new build service to
        setup scripts generation.

        * src/Makefile.header: Needed a trailing end-of-line

2001-02-15  Christian Arnault  <arnault@lal.in2p3.fr>

        * src/cmt_cvs.cxx (class CvsImplementation): Fix misuse of
        checkout_package arguments (confusion between package path and
        checkout directory)

2001-02-26    <arnault@lal.in2p3.fr>

        * src\cmt_parser.cxx (install_test_setup_scripts): use mktemp for
        setup scripts.

        * mgr\requirements: Suppress local private configuration of
        MSVC++. It has to be done previously to operate on CMT (even
        before making the INSTALL.bat)

2001-02-26  Christian Arnault  <arnault@lal.in2p3.fr>

        * src/cmt_deps_builder.cxx ((char* ptr,
                              state_def& state,
                              const cmt_string& dir_name,
                              int current_path_index,
                              const CmtSystem::cmt_string_vector& include_paths,
                              const CmtSystem::cmt_string_vector& substitutions,
                              CmtSystem::cmt_string_vector& all_deps,
                              CmtSystem::cmt_string_vector& deps)
        * src/cmt_generator.cxx ((const cmt_string& file_name)

        Rollback recent change to work on cmt_strings rather than char* to
        restore speed.

2001-02-15  Christian Arnault  <arnault@lal.in2p3.fr>

        * src/cmt_generator.cxx (build_dependencies): Restore the
        mechanism that takes into account the arguments, and the source
        list when -all_sources option is provided.

        * mgr/requirements: change /machine:I386 into /machine:IX86 as
        link option for VisualC

2001-02-13    <arnault@lal.in2p3.fr>

        * src\cmt_generator.cxx (build_dependencies): Do not require the
        source list from the arguments. Instead, get the sources directly
        from the constituents definition.

        The "cmt build dependencies" now only requires the constituent name. 

        * src\cmt_deps_builder.cxx: Read files at once into a cmt_string
        and work from the text instead of reainf line by line from the file.

        Install the detection of fortran include statements

2001-02-06    <arnault@lal.in2p3.fr>

        * src\cmt_use.cxx: clean up space & tabs

        * cmt_parser.cxx (parse_requirements_text): Abort the parser in
        case of error, but only for check configuration command.

        * NMakefile.header (lex_echo): Add -quiet option to cmt command
        except cmt check configuration
        
        * constituents.nmake: Add -quiet option to cmt command

2001-01-30    <arnault@lal.in2p3.fr>

        * all dsp fragments : suppress the Win32 Release
        configuration. Only keep the Win32 Debug. This makes possible the
        generation of msdev using the syntax cmt build msdev
        -tag=VisualCdbg

2001-01-30    <arnault@lal.in2p3.fr>

        * mgr/cmt_buildcvsinfos.py: first attempt to make the cvs script
        written in Python

        * mgr/requirements: Consistently base Windows tag on VisualC rather
        than WIN32

        upgraded setup.tcsh setup.zsh

        introduced cmt show include_dirs
        
        introduced cmt show constituent <name>

        bug in Pattern::add : overridden patterns were not cleared.

        cmt config must recursively get used packages (at least to get patterns)

        introduced cmt show pattern_names (at least for completion mechanisms)        
          new action : action_show_pattern_names

        experimental work started on build triggers
        
          macro build_triggers
                implied_library_prefix
                implied_library_sufffix

          new library option -triggers
          new constituent attribute build_triggers
          new fragment dependencies_and_triggers for libraries

        bug in cmt_system.cxx::scan_dir

        Recursively get all requirements file in cmt config action


        Changed strategy for argument parsing error detection
        
2001-01-30    <arnault@lal.in2p3.fr>

        * cmt_use.cxx ((const cmt_string& from_path) : bug in detection of
        "use pack " without version specification at all (ie equiv. to
        *). We needed to check we are on a real CMT package.

        * cmt_constituent.cxx (class action_iterator): Expand the macros
        before acting upon a constituent specification. Each expanded word
        may then result in several words. Thus the line parser is
        re-implemented through a local operator class "action_iterator",
        in charge of filling up a new constituent object from the expanded
        statement. (Note that this mechanism could perfectly be reused for
        other statements eg "use" !!!)

        * cmt_parser.cxx (set_standard_macros): Implement all_constituents
        and all_constituentsclean unconditionally.

        * NMakefile.header (checkuses): if defined statements require that
        the macro to test is provided without quotes.

        * cmt_generator.cxx: Apply the new convention of installing object
        files into $(bin)${CONSTITUENTS} also for applications (was only
        done for libraries)

        * cmt_parser.cxx (print_context): Take the current CONFIG name
        from CmtSystem::get_cmt_config rather than recursively calling
        "cmt system", when generating setup scripts.

        * cmt_cvs.cxx (class CvsImplementation): Use '/' ínstead of
        CmtSystem::file_separator for CVS-only file specs.

2000-12-26    <arnault@lal.in2p3.fr>

        * cmt_fragment.h (class Fragment and FragmentHandle): Install all
        variants of (win)copy methods that act upon a cmt_string instead
        of a FILE*.

        * cmt_model.cxx: Create the implementation file for CmtModel 

        * cmt_model.h (class CmtModel): Create the CmtModel class

        * cmt_parser.cxx (do_expand_model): Add the new command verb :
        'expand model' and all associated features
        (do_expand_model): call the CmtModel::expand
