Since I'm using subversion, I've never really read the FM, because it's so easy to use. Some days ago I discovered one interesting advanced feature. That is the so-called svn propset command, with it's svn:eol-style buddy. Why this one in particular? Because I remember having fought several times in cross-platform projects; the typical case is when one file is edited or created on Microsoft Windows (and so, most of the time with "\r\n" for the end of lines), which is then modified in another operating system like Unix or GNU/Linux: it produce strange output depending on the editor software. Anyway, svn:eol-style is the solution; apply this command over your files:

svn propset svn:eol-style native myFile

and then, the next one who will checkout, will obtain a file with the proper line ending, depending on his operating system; for example "\n" on GNU/Linux and "\r\n" on Microsoft Windows.

Really useful I think.
