# Packaging simexec.c

## License

Simexec is Public Domain so there are basically no barriers when it comes to
licensing. And if you somehow violate my already-forfeited copyright, I promise
I won't sue you.

## Files

Simexec is a single C file (`simexec.c`) that builds to a single executable,
which should be named `simexec` and placed in a user-accessible binaries
directory. A `Makefile` is provided as courtesy but isn't really necessary.

The `src/simexec` directory can be moved to a system sources directory if you
wish to keep the source on hand; it doesn't reference anything else in the
repository.

The included manual page, `simexec.1` can be placed in the appropriate manual
pages directory. If it displays weirdly feel free to e-mail me and I'll attempt
to fix it.

## Compilation

On systems that provide `<sysexits.h>`, the following is all that's needed:

```
cc -o simexec simexec.c
```

If you're not sure whether your system provides `<sysexits.h>`, try it and see.
If it doesn't work, compile `simexec.c` with the following:

```
cc -DEX_USAGE=1 -o simexec simexec.c
```

Other than `<sysexits.h>` simexec(1) only relies on headers found in the C
standard library. Outside of POSIX environments `simexec.c` probably won't work
but it wouldn't be of much use anyway.
