FishEye content-indexing for text files only?

[brbennett]

Using a trial fecru 4.4.1 on a Windows server with an hsql database. We're interested in the text content search feature for Subversion, but just ran across this: https://confluence.atlassian.com/fisheye/text-file-size-limiting-298976914.html. I've got a lot of files not marked with any mime-type and we consider those as text and believe that Subversion is as well (e.g. a ".map" file contains XML.) I'm aware of the raw-mime.types file and have added map to the text/plain list and am testing that now. My concerns are:

1. The raw-mime.types appears to be a system-wide parameter for FishEye. So *.map in one repository may be text, but binary in another.

2. Is there a way (e.g. a tool) that could scan a Subversion repository and report on the mime types and extensions it is finding?
