DESCRIPTION="single-file public domain (or MIT licensed) libraries for C/C++"
This could be anything.
I suggest something like
DESCRIPTION="C/C++ libraries to read and write bitmap files"
please adjust it to what these libraries are for.
The description came from Github.
It also has code for Vorbis, lexical parsing, Truetype, a text editor framework, an sprintf alternative, ... so just "bitmap files" is also not correct.
I'd suggest 'another pointless NIH used by n packages' (usually n=1).
