Simply: What is some good free Wiki software that can be quickly/easily ported over to confluence?
More specifically: We need something free that we can use to build up a repository of documentation, possibly importing from our existing word documents and Perl POD documentation. We are using Atlassian's Jira, so the business owners will eventually want the option to switch to Confluence (so they can use it as a massive enterprise solution for everything), but for the immediate future, the developers really need something that can give them a lift with building easy-to-find code documentation, as it's becoming a training issue.
Thoughts: Knowing that Confluence uses MySQL, we could potentially use something that sits on top of that and attempt to convert in the future. I've found a few posts about scripts to convert MediaWiki to Confluence, and this Confluence plugin for importing content. I realize this is potentially subjective, but I didn't know if there was an obvious "duh" tool out there for quickly converting one system to another when it came to wiki content, specifically from anything to confluence, or if a universal conversion project existed that covered those needs.
