Here are some of the features and notes about PmWiki's design decisions. Many of these derive directly from the PmWikiPhilosophy and lots of discussion on the mailing lists?.
- PmWiki:FlatFileAdvantages - why PmWiki uses flat files to store pages instead of an SQL database
- PmWiki:HierarchicalGroups - why PmWiki doesn't support nested groups
- PmWiki:PageLocking - how PmWiki works without locking pages (see also simultaneous edits?)
- PmWiki:SearchImprovements - why PmWiki has a native search engine
- PmWiki:FilePermissions - some information about PmWiki's file permission settings
- PmWiki:WikiGroupMotivation - why WikiGroups

Why doesn't PmWiki use hierarchical / nested groups?
It essentially comes down to figuring out how to handle page links between nested groups; if someone can figure out an obvious, intuitive way for authors to do that, then nested groups become plausible. See DesignNotes and PmWiki:HierarchicalGroups?.
Why don't PmWiki's scripts have a closing ?> tag?
All of PmWiki's scripts now omit the closing ?> tag. The tag is not required, and it avoids problems with unnoticed spaces or blank lines at the end of the file. Also, some file transfer protocols may change the newline character(s) in the file, which can also cause problems. See also the Instruction separation page in the PHP manual.
