     During the last ETF meeting, I was asked about the handling of quoted and
     unquoted file names in library mapping files in the NC-Verilog implementation.
     I have made some inquiries, and here is what I was told:

     Steve:
     
     Funny (or coincidental) that you should ask since I just fixed up the
     lib.map parser wrt handling names in double quotes.
     
     For any name (library name, file name, cell name, instance name, etc.)
     we require quoting if
     
     1) it contains /*
     Note: */ can appear in a name without quoting, it
     only ends a comment string when preceded by a non-quoted /*
     
     2) it contains any "special" characters:
     <space> , ( ) ' < > ` \ } { = / & | ~ : ; ] [
     
     Note: if a name contains any of these other than space,
     it can be either quoted or start with \ to indicate an escaped name.
     
     It does not appear that currently I allow <tab> in this list of special
     characters (for quoting only)...I think I need to add it.
     Should \n also be included or is that too goofy?
     
     I should point out that keywords can not be quoted (it will mess up the
     parser if you quote them!)
     
     We do support the funky Windows backslash directory delimiter (OK, I
     should say that the code attempts to support this, but I have no idea if
     any tests were run on windows to check, I do think PV runs some tests on
     windows, though).
