这是一个同样来自贝尔实验室的和UNIX有着渊源的操作系统, 其简洁的设计和实现易于我们学习和理解

 Directory dpost is DWB 3.3 version without UTF changes. dpost.utf is
 stuff for Plan 9. Both build and install dpost, so only pick one. The
 makefile I sent (postscript.mk) builds dpost.utf.

 Left READING set to ONEBYTE in common/gen.h. Expect dpost errors unless
 'x E UTF' is added to troff output or READING set to UTFENCODING. Easy
 to make 'x E UTF' anything else too.

 Left RUNELIB defined in common/rune.h so rune.c stuff is used when
 dpost.utf is built.

 UTF.enc is in directory psencoding. Install and link to Default.enc on
 Plan 9.

 Carmela requested two new characters: \(bs for backslash and \(dq for
 double quote. Both are in devLatin1 and devpost tables. Carmela also
 asked for a bunch of her devpost accent characters in devLatin1. Added
 them to the end of the devLatin1 tables.

 A word of warning about devLatin1. Carmela, Peter and others complained
 about - and hyphens being too long in the Latin1 fonts. I used Abode's
 choice but nobody liked it. New devLatin1 tables use a smaller character
 for hy. Looks better (I guess) but a width change affects line and page
 breaks!! Not sure what you want to do. Complaints on this one go to
 npn and carmela!!!

 Didn't take your suggested pathname change in download. Didn't want to
 risk breaking Unix 4.0 lp. What's there is bogus but was only for Unix
 4.0. The -r option accomplishes something similiar but needs a full path.

 postio.mk is very different and not tested on V9.
