552    <li class="new">Allow simultaneous/parallel builds for multiple binary tags
553    (used suggestions from Pere, Stefan, and Andrea):
554    <pre>- build all the makefiles in the binary tag directory
555- implement a locking mechanism
556The mechanism is in effect for CMT documents if
557macros lock_command, unlock_command are set to non-empty strings (default).
558Then, command ${lock_command} ${CONSTITUENT}${lock_suffix} is run by CMT to create the lock file in the package cmt directory
559before the document ${CONSTITUENT} is built,
560and command ${unlock_command} ${CONSTITUENT}${lock_suffix} is run by CMT to remove the lock file
561after the document ${CONSTITUENT} is built.
562The assumption is that while CMT applications, and libraries for different binary tags deal with different files,
563documents for different binary tags may deal with (e. g., build, install)
564the same files (e. g., header files). The locking mechanism is to ensure the documents are done one at a time</pre></li>
565    <li class="new">Implement an optional header file filter mechanism to replace
566        header files matching a pattern with a stamp file when calculating files dependencies
567    <pre>The mechanism is in effect if there is a package which
568- sets macro &lt;package&gt;_header_file_filter (to a regular expression)
569- sets macro &lt;package&gt;_header_file_stamp to a path of an existing file
570or file $(PACKAGE_ROOT)/cmt/cmt_header_file.stamp exists.
571Then, each header file whose path matches one of the regular expressions (if several packages activate the mechanism)
572is replaced with the corresponding stamp file in the dependency calculation and
573its dependencies are not examined. This may reduce the dependencies calculation time significantly.
574Example:
575macro Boost_header_file_filter $(Boost_home)/include/boost-$(Boost_file_version)
576macro Boost_header_file_stamp $(Boost_home)/include/boost-$(Boost_file_version)/boost/any.hpp
577The dependencies of the source files including Boost header files will only include the any.hpp file path.
