# This script generates resource files.
# Usage: ./resource.sh <file>
# Resource file is printed to stdout.
# Usable variables (<file> is stripped from path and extension):
#    const char *<file>_rc; // File content in binary format
#    const unsigned <file_rc_size; // File size
# Examples:
#    (file: dumps/test.out content: "ahoj")
#    ./resource.sh dumps/test.out
#    static const unsigned test_rc_size = 4;
#    static const char test_rc[] = { 'a', 'h', 'o', 'j', '\0' };
