The FreeMED Billing Project (FreeB) is a spin off project from the orginal FreeMED code. Its purpose is to have the capablility to elegantly handle the nightmare that is Medical Billing.
FreeMED Billing has at its core an XML Programming language that compiles to Perl code. Someday it be a compiler written in Perl that compiles to python... But that is not for today.

Why was the FreeMED Billing Project Spun off from FreeMED?

Two Reasons.
1. It became apparent that PHP could not handle the low level printer, fax and modem control to the degree that will be required for a really good billing system. Perls CPAN collection makes too many things easy. Perl is a high level programming language but is also designed to work with low level text munging. Its perfect for this application.

2. Both OSCAR, TORCH and GNUMED have expressed interest in having a really good billing system. Making it a meta project makes sense for everybody. What I would really like is for it to someday work like OpenSSH... A good implementation that everybody uses. That is in the spirit of Free Software.
