I've got some files in a repo that I don't want tracked, is it possible to remove them without removing the actual files from the filesystem?
This would be equivalent to git's rm --cached.
If you need to remove the file from Mercurial history as well, here's a stackoverflow question on how you do this: https://stackoverflow.com/questions/3558365/mercurial-remove-file-from-all-changesets/
I believe you can simply ignore them by placing them in a .hgignore file in the folder.
