Re: [MacPerl] Why does MacPerl 5.18r4 install SysErrs.err?

[Taylor Leaming <Taylor_Leaming-RZLA60@email.sps.mot.com>]

I agree.  I use (UNIX) Perl quite a bit at work, but I didn't install it and
don't administer it, so I only read the man page when I need them.  Consequently,
I had never even heard of these two files.

However, I am *glad* I inquired about these files, because now I know what they
are and where they came from.  I almost deleted them.

These files are several years old and pretty nondescript.  So, there are few
clues as to their origin, and no obvious association with MacPerl.

A suggestion:  

    How about adding 'vers' resource to these files to associate them with
    MacPerl in the Get Info box.  Maybe even an Installer Log file or the
    MANIFEST.appl file in the installation.
