38 | ** SCCS.C -- human-oriented front end to the SCCS system. | |
39 | ** | |
40 | ** Without trying to add any functionality to speak of, this | |
41 | ** program tries to make SCCS a little more accessible to human | |
42 | ** types. The main thing it does is automatically put the | |
43 | ** string "SCCS/s." on the front of names. Also, it has a | |
44 | ** couple of things that are designed to shorten frequent | |
45 | ** combinations, e.g., "delget" which expands to a "delta" | |
46 | ** and a "get". | |
47 | ** | |
48 | ** This program can also function as a setuid front end. | |
49 | ** To do this, you should copy the source, renaming it to | |
50 | ** whatever you want, e.g., "syssccs". Change any defaults | |
51 | ** in the program (e.g., syssccs might default -d to | |
52 | ** "/usr/src/sys"). Then recompile and put the result | |
53 | ** as setuid to whomever you want. In this mode, sccs | |
54 | ** knows to not run setuid for certain programs in order | |
55 | ** to preserve security, and so forth. | |
56 | ** | |
57 | ** Usage: | |
58 | ** sccs [flags] command [args] | |
59 | ** | |
60 | ** Flags: | |
61 | ** -d<dir> <dir> represents a directory to search | |
62 | ** out of. It should be a full pathname | |
63 | ** for general usage. E.g., if <dir> is | |
64 | ** "/usr/src/sys", then a reference to the | |
65 | ** file "dev/bio.c" becomes a reference to | |
66 | ** "/usr/src/sys/dev/bio.c". | |
67 | ** -p<path> prepends <path> to the final component | |
68 | ** of the pathname. By default, this is | |
69 | ** "SCCS". For example, in the -d example | |
70 | ** above, the path then gets modified to | |
71 | ** "/usr/src/sys/dev/SCCS/s.bio.c". In | |
72 | ** more common usage (without the -d flag), | |
73 | ** "prog.c" would get modified to | |
74 | ** "SCCS/s.prog.c". In both cases, the | |
75 | ** "s." gets automatically prepended. | |
76 | ** -r run as the real user. | |
77 | ** | |
78 | ** Commands: | |
79 | ** admin, | |
80 | ** get, | |
81 | ** delta, | |
82 | ** rmdel, | |
1864bcbd | 83 | ** cdc, |
27e713f7 EA |
84 | ** etc. Straight out of SCCS; only difference |
85 | ** is that pathnames get modified as | |
86 | ** described above. | |

27e713f7 EA |
104 | ** use in makefiles. |
105 | ** fix Remove a top delta & reedit, but save | |
106 | ** the previous changes in that delta. | |
107 | ** | |
108 | ** Compilation Flags: | |
109 | ** UIDUSER -- determine who the user is by looking at the | |
110 | ** uid rather than the login name -- for machines | |
111 | ** where SCCS gets the user in this way. | |
56151b9e | 112 | ** SCCSDIR -- if defined, forces the -d flag to take on |
d266e8cb EA |
113 | ** this value. This is so that the setuid |
114 | ** aspects of this program cannot be abused. | |
56151b9e EA |
115 | ** This flag also disables the -p flag. |
116 | ** SCCSPATH -- the default for the -p flag. | |
27082f2b EA |
117 | ** MYNAME -- the title this program should print when it |
118 | ** gives error messages. | |
27e713f7 EA |
119 | ** |
120 | ** Compilation Instructions: | |
121 | ** cc -O -n -s sccs.c | |
27082f2b EA |
122 | ** The flags listed above can be -D defined to simplify |
123 | ** recompilation for variant versions. | |
