# hook or symlink it.

# NOTE, things to do manually (once) before running this script:
# - modify the categories in the for loop with your own.
#
# usage: sh example_post-receive.sh [reponame]
#
# if reponame is not set the basename of the current directory is used,
# this is the directory of the repo when called from the post-receive script.

# NOTE: needs to be set for correct locale (expects UTF-8) otherwise the
#       default is LC_CTYPE="POSIX".
