3 projects need Perl to host, listed alphabetically. They are ikiwiki, Movable Type and Webmin. Mostly content management systems, site and docs generators and wikis and collections, of 4 categories in all. 77 records do not record this field, and cannot appear here either way. For 206 the question does not apply. Counts only projects with momentum; the full list has the rest.
I
ikiwikiWiki compiler that builds wiki pages into a static website, storing page history in a revision control system, with blogging support.
M
Movable TypeCommercial publishing and blogging system from Six Apart that publishes static pages, dynamic pages or both from templates.
W
WebminWeb-based administration tool for Unix-like servers that configures system files and server applications such as Apache HTTP Server, BIND and MySQL.
Which of these is best?
We can't tell from here. What suits an editor-heavy marketing site can be wrong for a static documentation site. The list is alphabetical and nobody paid for a place on it.
