NAME

mkc_check_custom - run user's custom checks.

SYNOPSIS

mkc_check_custom [-r] sourcefile
mkc_check_custom cmd [args...]
mkc_check_custom -h

DESCRIPTION

If cmd is executable mkc_check_custom runs cmd args. Otherwise it tries to compile sourcefile and output 1 if compilation succeeded and 0 otherwise. If -r option was applied it runs a compiled program. What type of compiler to use depends on sourcefile extension. '.c' corresponds to ${CC} (C language), '.cc', '.cxx', '.C' and '.cpp' correspond to ${CXX} (C++ language).
