# 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 )
#
# This simply receives text on stdin and replaces any occurrence of "@" by
# " _ " to obfuscate emails. Not the most sophisticated algorithm (for now),
# but laziness and time are two important factors.
# It still helps with receiving email only from the wealthy Nigerian princes.
# I need to make money, too.
