It is Perl specific, but Jeff Pinyan has created a
utility to take an RE and come back with an explanation
of how it is structured.  You can access it at
http://www.crusoe.net/~jeffp/YAPE/OGRE.cgi (or download
it and run it offline - which will be much quicker).

It should offer you a good explanation of what this RE
means.  To its explanation I will add that the engine
does a brute-force search for finding a way to match,
starting with the beginning of the string and the
beginning of the RE.  Therefore the .{1,50} rule is
greedy and takes precedence (ie it prefers to find a
match where that is as long as possible, only
backtracking to less desirable matches if it cannot do
that.)

Cheers,
Ben
