Linefeed conversion
One of the less enjoyable things about Subversion is that it is quite picky about linefeed consistency in committed files. Are you using CRLF or just LF? Personally I don't really care as most editors can handle this. I'm sure that there is a perfectly good reason for Subversion's enforcing this, but it is a hassle when you have a bunch of modifications to process and the commit keeps failing part way through telling you that yet another file is inconsistent. I came across a little free utility called
ToFroWin CR/LF converter that has saved me hours of tedious effort to ensure that line feeds are set consistently for a set of files. It plugs into Windows Explorer allowing you to easily convert selected files back and forth between different linefeed formats.
