This is wimlib version 1.0.0 (September 2012). wimlib can be used to read,
write, and mount files in the Windows Imaging Format (WIM files). These
files are normally created by using the `imagex.exe' utility on Windows,
-but this library provides a free implementetion of imagex for UNIX-based

+ WIM FILES
+
+A Windows Imaging (WIM) file is an archive. Like some other archive formats
+such as ZIP, files in WIM archives may be compressed. WIM archives support two
+Microsoft-specific compression formats: LZX and XPRESS. Both are based on LZ77
+and Huffman encoding, and both are supported by wimlib.
+
+Unlike ZIP files, WIM files can contain multiple independent toplevel directory
+trees known as images. While each image has its own metadata describing a
+directory tree and file access modes, files are not duplicated for each image;
+instead, each file is included only once in the entire WIM. Microsoft did this
+so that in one WIM file, they could do things like have 5 different versions of
+Windows that are almost exactly the same.
+
+Microsoft provides documentation for the WIM file format, XPRESS compression
+format, and LZX compression format. The XPRESS documentation is acceptable, but
+the LZX documentation is not entirely correct, and the WIM documentation itself
+is very incomplete and is of unacceptable quality.
+
+A WIM file may be either stand-alone or split into multiple parts.
