#!/bin/sh

# Script to run cppcheck
#
# Usage: /path/to/run_cppcheck.sh [ -v CPPCHECK_VER] [<extra_opts_and_dirs>]
#
# - If <extra_opts_and_dirs> is missing, '.' is assumed
# - If -v CPPCHECK_VER is specified, that version of cppcheck is run from
#   ~/cppcheck.local (whether or not it's there!). Use install_cppcheck.sh
#   to install a new version.
#
# Environment (all optional):-
#
# CPPCHECK       : Override the default cppcheck command ('cppcheck').
#                  Ignored if -v is specified
# CPPCHECK_FLAGS : Override the default cppcheck flags

INSTALL_ROOT=~/cppcheck.local

# Figure out CPPCHECK setting, if any. Currently '-v' must be the first
# argument on the command line.
