# pre-commit-hook
#
# Description
# pre-commit hook for git.
# Copy or link this file as ".git/hooks/pre-commit"
#
# Eg,
# (
# cd $WM_PROJECT_DIR/.git/hooks &&
# ln -sf ../../bin/tools/pre-commit-hook pre-commit
# )
#
# Hook receives: empty
#
# Checks for
# - trailing whitespace and non-standard line endings
# - illegal code, e.g. <TAB>
# - columns greater than 80 for *.[CH] files
# - non-standard code patterns
# - missmatched header #ifndef/#define names
# - incorrect copyright statements
#
# Note
# Using "git commit --no-verify" it is possible to override the hook.
#
# By supplying arguments to the hook, it can also be used to manually
# test the specified files/directories for standards conformance.
