FORM is a Symbolic Manipulation System. It reads symbolic expressions from files and executes symbolic/algebraic transformations upon them. The answers are returned in a textual mathematical representation. As its landmark feature, the size of the considered expressions in FORM is only limited by the available disk space and not by the available RAM.
FORM's original author is Jos Vermaseren of NIKHEF, the Dutch institute for subatomic physics. Other people that have made contributions can be found in the file "AUTHORS".
See the file "INSTALL".
Information about copying and licencing of this software can be found in the file "COPYING".
More background information, the latest version and a collection of FORM programs can be found on the official FORM website: http://www.nikhef.nl/~form.
Bugs can be reported via the Issue Tracker of Github.
