# This script updates the version stamp in configure.in, and also in assorted
# other files wherein it's not convenient to obtain the version number from
# configure's output.  Note that you still have to run autoconf afterward
# to regenerate configure from the updated configure.in.
#
# Usage: cd to top of source tree and issue
#	src/tools/version_stamp.pl MINORVERSION
# where MINORVERSION can be a minor release number (0, 1, etc), or
# "devel", "alphaN", "betaN", "rcN".

# a new development version.
