slackbuilds_ponce/libraries/libb64

libb64 is a library of ANSI C routines for fast encoding/decoding data
into and from a base64-encoded format. C++ wrappers are included,
as well as the source code for standalone encoding and decoding
executables.

Base64 uses a subset of displayable ASCII characters, and is therefore
a useful encoding for storing binary data in a text file, such as XML,
or sending binary data over text-only email.
