PostScript files that go in $(POSTLIB). Several, like forms.ps, are used by most translators supplied in this package. Most PostScript files only used by a single translator (e.g. the prologue) have been been moved into the appropriate source directory. Files that end in .enc support alternate character sets (e.g. ISO Latin 1 alphabet). The implementation is left open, but typically redefines findfont. That approach works because findfont is a procedure rather than an operator, so it's not affected by bind. Also can't depend on having a systemdict definition for findfont. It's in userdict on Version 48.0 VT600s.
