# - Makes index for repositories in a single directory.
# - Makes static pages for each repository directory.
#
# NOTE, things to do manually (once) before running this script:
# - copy style.css, logo.png and favicon.png manually, a style.css example
#   is included.
#
# - write clone url, for example "git://git.codemadness.org/dir" to the "url"
#   file for each repo.
# - write owner of repo to the "owner" file.
# - write description in "description" file.
#
# Usage:
# - mkdir -p htmldir && cd htmldir
# - sh example_create.sh

# path must be absolute
