While it is simple to include an svn keyword (E.g. "$Ig: $") in a perl comment, I want to assign it to a string variable so I can print it out or include it in a log file etc.

Various warnings etc. from the compiler suggested I declare and assign a value to it first, otherwise perl complained I was using it before it was assigned.

That was relatively trivial to fix (albeit perhaps not "properly" - see below), the remaining problem is the trailing (dangling) '$' in the string. I can't escape it using a backslash as svn doesn't find it. Ending the string with $\\" also produces a warning (uninitialized value). If I use something like the following:

our $Id = "";
our $IdEnd = "";

$script_version = "$Id: Myob2010_mpbudget.pl 32 2010-05-28 03:57:52Z a
+ndrew $IdEnd";

The ending $IdEnd is not interpreted as an empty string and appears literally, which of course I could just strip off for output, but I am hoping there is a more elegant solution.

I have ended up using a "double dollar", so the svn keyword before expansion is "$Id: $$"

Can this be improved on ?
