# simple script to be used in hooks

# copy it to the current directory when the test starts:

#

#     cp "$TESTDIR"/printenv.py .

#

# put something like this in the repo .hg/hgrc:

#

#     [hooks]

#     changegroup = python ../printenv.py <hookname> [exit] [output]

#

#   - <hookname> is a mandatory argument (e.g. "changegroup")

#   - [exit] is the exit code of the hook (default: 0)

#   - [output] is the name of the output file (default: use sys.stdout)

#              the file will be opened in append mode.
