    6 Cette page est destinée à rassembler la "foire aux questions" sur les sujets divers ou transversaux (création de compte, certificats, ...). Pour ajouter une nouvelle entrée il suffit d'ajouter une entrée dans la catégorie ad-hoc ou de créer une nouvelle catégorie si nécessaire, en respectant le format suivant :
     14=== What is CMT ? ===
    715
    8  * Les entrées sont des paragraphes de troisième niveau (titre encadré par {{{===}}}).
    9  * Les catégories sont des paragraphes de deuxième niveau (titre encadré par {{{==}}}).
     16[http://www.cmtsite.org/ CMT](__C__onfiguration __M__anagement __T__ool) is a configuration management environment, based on some management conventions and comprises several shell-based utilities. It is an attempt to formalize software production and especially configuration management around a package-oriented principle.
     17
     18The environment provides conventions (for naming packages, files, directories and for addressing them) and tools for automating as much as possible the implementation of these conventions. It permits to describe the configuration requirements and automatically deduce from the description the effective set of configuration parameters needed to operate the packages (typically for building them or using them).
     19
     20=== What is a package ? ===
     21
     22The notion of packages represents hereafter a set of software components (that may be applications, libraries, tools etc...) that are to be used for producing a system or a framework. In such an environment, several persons are assumed to participate in the development and the components themselves are either independent or related to each other.
     23

     25
     26See: [http://www.cmtsite.org/install.html Install]
     27
     28=== Are there copyright restrictions on the use of CMT ? ===
     29
     30Not really. CMT is provided as an Open-Source product, with available sources, and is opened to any contribution from anybody.
     31
     32See the license page [http://www.cecill.info/licences.en.html agreement] to find further explanations and a link to the full text of the license.
     33
     34=== How do I get documentation on CMT ? ===
     35
     36All documentation is available on-line, starting at [http://www.cmtsite.org/documents.html Documents].
     37
     38=== Is there a mailing list devoted to CMT ? ===
     39
     40There is a mailing list, [http://www.cmtsite.org/discussion.html mailing list].
     41
     42=== I've never used CMT before. Is there a CMT tutorial? ===

     67CMT is an academic project aimed at providing support to the software developments in the context of large physics experiments ([http://atlas.web.cern.ch atlas],[[BR]][http://lhcb.web.cern.ch/lhcb/ lhcb], ...).
    1968
    20 La fermeture d'un compte se fait à la demande de son responsable de groupe. Il ne peut être rouvert qu'avec l'accord (ou à la demande) de ce responsable.
     69Although it is currently used by Physics experiments, it is strongly required to stay experiment neutral, and this requirements is fully endorsed in its internal design (eg by ensuring that all possible customizations can always be performed without modifications to the kernel).
    2170
     71This kind of requirements also implies that portability or modularity issues (including environment independance) are assigned a quite high priority.

     73=== What are the supported platforms ? ===
     74
     75CMT has been ported and tested on a wide range of machines/operating systems, including:
     76
     77 * DEC-Unix V4.0
     78 * HP-UX-10 (several types of platforms)
     79 * AIX-4
     80 * Solaris
     81 * IRIX
     82 * Several variants of LynxOS
     83 * All variants of Linux (RedHat, Debian, SuSe, ScientificLinux, ...)
     84 * Windows 95/98/NT/Windows2000 in various environments:
     85    * CYGWIN_NT-5.1 environment
     86    * nmake based environment
     87    * MSDev/VisualC 6 environment
     88    * MSDev/VisualC 7 environment
     89 * Darwin (Mac OS X)

     91== CMT's design ==
     92
     93= What are the architecture of the environment ? =
     94This environment is based on the fact that one of its packages (named CMT ) provides the basic
     95management tools. CMT , as a package, has very little specificities and as such itself obeys the
     96general conventions.
     97Then the complete software base is organized in terms of projects (or sub-projects ), containing
     98consistently managed package sets. Projects are localized either globally or individually:
     99globally using the environment variable CMTPROJECTPATH that describes all locations
     100where CMT projects can be found individually using the environment variable CMTPATH that describe all package areas where packages can be found Packages are localized respectively to the projects they belong to.
     101It should be noted that the choice of a location for installing CMT itself is totally independent of
     102the locations where projects are installed and managed.
     103
     104CMT is operated through one main user interface : the cmt command, which operates the CMT
     105conventions and which provides a set of services for :
     106 * creating a new package. This operation will create or check the local package directory tree and generate several minimal scripts (see the description of the create command),
     107 * describing or monitoring :
     108    * the relationships between the package and other packages
     109    * the configuration features either specified in the current package, or imported from related (used ) ones. (symbols, patterns, fragments)
     110    * the constituents of the package in terms of libraries, executables, or generated documents.
     111 * automatically generating the reconstruction scripts (makefiles ) from this description.
     112 * recursively acting upon the hierarchy of used packages.
     113
     114Several other utilities are also provided for some specific activities (such as the automatic
     115production of shared libraries, C prototypes, management of interactions between CVS and CMT
     116itself, the management of a similar architecture for Windows or OS9 , setting up protections for
     117packages (through locks) etc...).

     121== How to create a package ? ==
     122
     123 cmt create <package_name> <version>
     124
     125== Does the "requirements" file support comments ? ==
     126
     127Yes. A comment starts with a hash character (#) that is not part of a string literal, and ends at the end of the physical line.
