Seven files comprise ePiX: a header (epix.h), compiled library (libepix.a), and five shell scripts (epix, elaps, laps, flix, and keywords). Four of these files are generated at compile time, using variables found in the Makefile. In addition to the executable portions of the program, there are a few dozen sample files, configuration files, READMEs, and miscellaneous documentation. These components are placed into standard locations where they can find each other.
