// This program is used to pack arbitrary data into a C binary. It takes
|
|
// a list of files as an input, and produces a .c data file that contains
|
|
// contents of all these files as a collection of byte arrays.
|
|
//
|
|
// Usage:
|
|
// 1. Compile this file:
|
|
// cc -o pack pack.c
|
|
//
|
|
// 2. Convert list of files into single .c:
|
|
// ./pack file1.data file2.data > fs.c
|
|
//
|
|
// 3. In your application code, you can access files using this function:
|
|
// const char *mg_unpack(const char *file_name, size_t *size);
|
|
//
|
|
// 4. Build your app with fs.c:
|
|
// cc -o my_app my_app.c fs.c
