creating, modifying, extracting, and mounting files in the Windows Imaging
Format (WIM files). wimlib and its command-line frontend 'wimlib-imagex'
provide a free and cross-platform alternative to Microsoft's WIMGAPI, ImageX,

wimlib is mainly used on x86 and x86_64 CPUs, but it should also work on a
number of other GCC-supported 32-bit or 64-bit architectures. It has been

Currently, gcc and clang are the only supported compilers. A few nonstandard
extensions are used in the code.
