536    <li class="new">Allow simultaneous/parallel builds for multiple binary tags
537    (used suggestions from Pere, Stefan, and Andrea):
538    <pre>- build all the makefiles in the binary tag directory
539- implement a locking mechanism
540The mechanism is in effect for CMT documents if
541macros lock_command, unlock_command are set to non-empty strings (default).
542Then, command ${lock_command} ${CONSTITUENT}${lock_suffix} is run by CMT to create the lock file in the package cmt directory
543before the document ${CONSTITUENT} is built,
544and command ${unlock_command} ${CONSTITUENT}${lock_suffix} is run by CMT to remove the lock file
545after the document ${CONSTITUENT} is built.
546The assumption is that while CMT applications, and libraries for different binary tags deal with different files,
547documents for different binary tags may deal with (e. g., build, install)
548the same files (e. g., header files). The locking mechanism is to ensure the documents are done one at a time</pre></li>
549    <li class="new">Implement an optional header file filter mechanism to replace
550        header files matching a pattern with a stamp file when calculating files dependencies
551    <pre>The mechanism is in effect if there is a package which
552- sets macro &lt;package&gt;_header_file_filter (to a regular expression)
553- sets macro &lt;package&gt;_header_file_stamp to a path of an existing file
554or file $(PACKAGE_ROOT)/cmt/cmt_header_file.stamp exists.
555Then, each header file whose path matches one of the regular expressions (if several packages activate the mechanism)
556is replaced with the corresponding stamp file in the dependency calculation and
557its dependencies are not examined. This may reduce the dependencies calculation time significantly.
558Example:
559macro Boost_header_file_filter $(Boost_home)/include/boost-$(Boost_file_version)
560macro Boost_header_file_stamp $(Boost_home)/include/boost-$(Boost_file_version)/boost/any.hpp
561The dependencies of the source files including Boost header files will only include the any.hpp file path.
