Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
pcre-config --version (return code: 0)
8.38
pcre-config --help (return code: 1)
Usage: pcre-config [--prefix] [--exec-prefix] [--version] [--libs] [--libs-posix] [--libs32] [--libs16] [--libs-cpp] [--cflags] [--cflags-posix]
