# FOR USE ONLY DURING NIGHTLY DEVELOPMENT BUILDS

# DO NOT COMMIT TO CVS AFTER RUNNING THIS SCRIPT

# This script is intended for use only during the preparation of master sources for nightly snapshot builds.
# It modifies autogen.sh to use an extended package version number containing the current date.
#
# This style of version number is particular to graphviz, and probably wouldn't be done this way if
# we were using SVN rather than CVS.  Also, it has obscure complications when we try to extend it to the Windows platform.
#
# For these reasons, we maintain this custom script here rather than in the generic package build scripts.
#
# This script should not be run for stable builds, and for development builds it should be run first after checkout:
#
#	cvs co graphviz2
#	cd graphviz2
#	./set_dev_version.sh
#	./autogen.sh
#	make dist
