Annotation of researchv10no/cmd/troff/devaps/README, revision 1.1

1.1     ! root        1: 
        !             2: Font and device tables for the APS-5 phototypesetter. For the time being
        !             3: only troff reads these files. The post-processor (daps) that's run in
        !             4: Jinny's code is forced to read the tables in /usr/lib/aps5/devaps because
        !             5: the ru character is bad on our disk. If troff and daps read the same tables
        !             6: all lines drawn with ru would be dashed. If it ever gets fixed we can get
        !             7: rid of the post-processor's tables.
        !             8: 
        !             9: 
        !            10: -------------------------------------------------------------------------------
        !            11: 
        !            12: 
        !            13:  1: The width of ru on the R, I, B, and S fonts is 12 units less than
        !            14:     Autologic's specifications. This eliminates the dashed line problems
        !            15:     we were having, provided only troff reads these tables.
        !            16: 
        !            17:  2: Added the en character to the I and B fonts so that font positions
        !            18:     1, 2, and 3 would all be the same size. Told users on other systems
        !            19:     to remove en from R since it's only used in our banners and that
        !            20:     seemed to be a less error prone process.
        !            21: 
        !            22:  3: Added xe, xt, and xk to DESC, GB, and GR files.
        !            23: 
        !            24:  4: Set the character code for bs in the S font to 0 so that the old
        !            25:     Bell System logo will be replaced by white space on the APS-5. Since
        !            26:     daps doesn't read these tables (when Jinny runs it) we need to be sure
        !            27:     the same thing is done in /usr/lib/aps5/devaps/S!
        !            28: 
        !            29:  5: Added the new ATT logo characters to DESC and the S font file.
        !            30: 
        !            31:  6: Fixed (probably overdid) the ascender/descender stuff. There's a
        !            32:     file called KERNING that's got all the required info. It's used
        !            33:     by fixkern and awk.script.
        !            34: 
        !            35:  7: Added the old Bell Logo to the DESC file and the S font as character
        !            36:     LB. We were getting quite a few requests for the character from CSO
        !            37:     customers. Still have \(bs replaced by white space.
        !            38:
