-- It adds gravatar icons to author names. It is designed to be used with the lua:

# script is very slow, in comparison.

# This script may be used with the email-filter or repo.email-filter settings in cgitrc.
#
# The following environment variables can be used to retrieve the configuration
# of the repository for which this script is called:
# CGIT_REPO_URL ( = repo.url setting )
# CGIT_REPO_NAME ( = repo.name setting )
# CGIT_REPO_PATH ( = repo.path setting )
# CGIT_REPO_OWNER ( = repo.owner setting )
# CGIT_REPO_DEFBRANCH ( = repo.defbranch setting )
# CGIT_REPO_SECTION ( = section setting )
# CGIT_REPO_CLONE_URL ( = repo.clone-url setting )
#
# It receives an email address on argv[1] and text on stdin. It prints
# to stdout that text prepended by a gravatar at 10pt.
