In file papco_files_needed.text we provide a short description of the main files which are needed by PaPCo. The files are roughly divided into four categories: PaPCo ``Core'', which is the main system and should not be altered by the user. PaPCo Lib, a set of utility files that could be recycled by other applications too. PaPCo modules, user written code that actually does plots, and PaPCo doc, for documentation.
