   Hello bean people!

   First of all, thanks for the script without which cvs log is basically
   useless. However, I wasn't able to run the script properly with
   cygwin/cvsnt. Cygwin looked for the script in "/cygdrive/c/Program
   Files/cvsnt/", and Perl couldn't handle the space in "Program Files"
   (classic issue it seems), resulting in the following error message:

   Can't open perl script "/cygdrive/c/Program": No such file or
   directory

   I asked about this on the cygwin mailing list (see thread at
   http://www.mail-archive.com/cygwin@cygwin.com/index.html#87229) and
   was told to put the $0 on the second line (exec perl) in quotes, which
   works fine.

   I don't know if this would break script execution on other systems. If
   so, you could mention this issue on the web site. If not, please fix!
   :)

   Thanks, Andreas
