# Please prefer the email-gravatar.lua using lua: as a prefix over this script. This
# 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.
