We use tortoise hg with Kiln. In my vs 2010 c# project there are some files that are part of the repository but I would like tortoise hg to ignore them when I make a commit.
When you do a TortoiseHG commit, there is a list of files with checkboxes by them. Deselect the files you do not want comitted.
Or, on the command line, do a commit of the form hg commit --exclude "pattern", where pattern is defined in the hg man page.
hg commit --exclude "pattern"
