2 # Toplevel configure.ac for the Modular C++ Build System
3 #=========================================================================
4 # Please read the documenation in 'mcppbs-doc.txt' for more details on
5 # how the Modular C++ Build System works. For most new projects, a
6 # developer will only need to make the following changes:
7 #
8 # - change the project metadata listed right below
9 # - update the list of subprojects via the 'MCPPBS_SUBPROJECTS' macro
10 # - possibly add subproject groups if needed to ease configuration
11 # - add more configure checks for platform specific configuration

23 # Project version information
24 #-------------------------------------------------------------------------
25 # Version information is meant to be managed through a version control
26 # system's tags and revision numbers. In a working copy the version will
27 # not be defined here (you should just use the version control system's
28 # mechanisms). When we make a distribution then we can set the version
29 # here as formed by the scripts/vcs-version.sh script so that the
30 # distribution knows what version it came from. If you are not using
31 # version control then it is fine to set this directly.
