// This program takes a list of files as an input, and produces C++ code that
// contains the contents of all these files as a collection of strings.
//
// Usage:
// 1. Compile this file:
// cc -o generate-translations-header generate-translations-header.c
//
// 2. Convert list of files into single header:
// ./generate-translations-header monero_fr.qm monero_it.qm > translations_files.h
//
// 3. In your application code, include translations_files.h, then you can
// access the files using this function:
// static bool find_embedded_file(const std::string &file_name, std::string &data);
// std::string data;
// find_embedded_file("monero_fr.qm", data);
#include <stdio.h>
#include <stdlib.h>
