showchar nonfunctional or undocumented

[Klaatu]

I spent some time trying to determine what the showchar script was for, and 
have so far failed. I'm wondering if anyone can provide guidance about what 
it's meant to do? 

>From reading it, it appears only to cat some postscript code with only nominal 
modification (nothing specific to the font or character name provided). It even 
seems to have Times-Roman hardcoded into it (maybe for rendering output?). 

I'm at a loss. There's no man or info page for it, and --help only provides 
the basic syntax. 

Thanks for a2ps!
