src/C/README.md

-About
------
-
-The libraries in this directory have been patched, extended, or otherwise modified from their original versions for use with binwalk.
-
-Specifically, libcompress42` contains code taken from the ncompress Unix utility and turned into a library. It is similar to the liblzw library (also ripped from ncompress source), but supports decompression of arbitrary data buffers and includes several useful wrapper functions. To the author's knowledge, this functionality is not available elsewhere as a standard library.
-
-Package mantainers should consult their particular distribution's rules on bundled code with regards to the above libraries.
-
-Installation
-------------
-
-These libraries will be built and installed by default, unless the `--disable-clibs` option is provided to the configure script.
-
-The libraries will be installed to the `lib` sub-directory of the binwalk Python module so as to not conflict with existing libraries on the system.
