Annotation of researchv10no/cmd/troff/devaps/README, revision 1.1.1.1

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: 
                     39: 
                     40: -------------------------------------------------------------------------------
