+FASDA aims to provide a fast and simple differential analysis tool
+that just works and does not require any knowledge beyond basic Unix
+command-line skills. The code is written entirely in C to maximize
+efficiency and portability, and to provide a simple command-line user
+interface.
+
+FASDA-utils is a collection of optional companion programs and
+scripts.  They are separated from the main FASDA distribution in order
+to keep FASDA packages minimal.
