# Distribution generator for git
#
# Usage: makedist version
# Example: makedist 5.4.1
# Example: makedist 5.3.5RC1
#
# To work, this script needs a consistent tagging of all releases.
# Each release of a package should have a tag of the form
#
#  php-X.Y.Z[sub]
#
# The distribution ends up in a .tar.gz file that contains the distribution
# in a directory called php-<version>.
# A .tar.bz2 file is also created.
