1/29    Looking through some Perl files, and I noticed some files with
        a line consisting of just a "1;" at the end.  What does that
        mean?  - perl newbie
        \_ return code.
           \_ thanks.
        \_ When you "require" another file, it runs through and expects a
           "true" value at the end.  ergo, 1;.  It's in effect a return code,
           but for a different reason.
           \_ thanks, makes sense now.
