Development version

You can install a development version using Mercurial

hg clone http://hg.malikania.fr/libbase64

Installation

The library is too small to be worth being installed system wide and as such there are no install target nor library generation. Instead, you should simply copy the files base64.c and base64.h to your project and start using the functions.

You can still run the test suite using make tests command.
