System Requirements

All that Pie requires to run is a run-time version of PHP, version 4.x or later, with the following modules compiled in:

• regex: Bundled Regex Library
• pcre-regex: (Perl Compatible Regular Expressions) Support

The web server's launched process also requires a file directory hierarchy (or several separate directories, that is) below which it may freely create and write files (see file structure).
