Usage is embedfiles [file to embed...] [-l {c}] [-o {outfile}]. To specify another language use the -l option (C is the only lang supported as of now). It creates a new file in the specified language and puts a byte array of the inputfile in. Example output:

Hello World!

#include <stdlib.h>
const char in.txt[] = {
  0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x57, 0x6f, 0x72, 0x6c,
  0x64, 0x21, 0x0a,
};
const size_t in.txt_len = sizeof(in.txt);

This project requires no libraries other than glibc or other implementations of libc. Run mkdir build && cd build && cmake .. and then make. This will produce the embedfiles binary.
