mkc_check_custom [-r] sourcefile

mkc_check_custom cmd [args...]

mkc_check_custom -h

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.
