# A tool/hook to run basic sanity checks on commits/patches for
|
|
|
# submission to Mercurial. Install by adding the following to your
|
|
|
# .hg/hgrc:
|
|
|
#
|
|
|
# [hooks]
|
|
|
# pretxncommit = contrib/check-commit
|
|
|
#
|
|
|
# The hook can be temporarily bypassed with:
|
|
|
#
|
|
|
# $ BYPASS= hg commit
|
|
|
