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

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