23 ;;
|

24 ;; o Match multiple man pages using TOPIC as a simple pattern
|
|
|
25 ;; o Search unformatted pages, even when formatted matches are found
|
|
|
26 ;; o Query the user as to which pages are desired
|
|
|
27 ;; o Use of the prefix arg to toggle/bypass the above features
|
|
|
28 ;; o Buffers named by the first topic in the buffer
|
|
|
29 ;; o Automatic uncompress for compressed man pages (.Z, .z, and .gz)
|
|
|
30 ;; o View the resulting buffer using M-x view mode
|
|
|
31 ;;
|
|
|
32 ;; Modified 16-mar-91 by Jamie Zawinski <jwz@lucid.com> to default the
|
|
|
33 ;; manual topic to the symbol at point, just like find-tag does.
|
|
|
34 ;;
|
|
|
35 ;; Modified 22-mar-93 by jwz to use multiple fonts and follow xrefs with mouse.
|
|
|
36 ;;
|
|
|
37 ;; Modified 16-apr-93 by Dave Gillespie <daveg@synaptics.com> to make
|
|
|
38 ;; apropos work nicely; work correctly when bold or italic is unavailable;
|
|
|
39 ;; reuse old buffer if topic is re-selected (in Manual-topic-buffer mode).
|
|
|
40 ;;
|
|
|
41 ;; Modified 4-apr-94 by jwz: merged in Tibor Polgar's code for manpath.conf.
|
|
|
42 ;;
|
|
|
43 ;; Modified 19-apr-94 by Tibor Polgar <tlp00@spg.amdahl.com> to add support for
|
|
|
44 ;; $PAGER variable to be emacsclient and properly process man pages (assuming
|
|
|
45 ;; the man pages were built by man in /tmp. also fixed bug with man list being
|
|
|
46 ;; backwards.
|
|
|
47 ;;
|
|
|
48 ;; Modified 23-aug-94 by Tibor Polgar <tlp00@spg.amdahl.com> to add support for
|
|
|
49 ;; displaying only one instance of a man page (Manual-unique-man-sections-only)
|
|
|
50 ;; Fixed some more man page ordering bugs, bug with Manual-query-multiple-pages.
|
|
|
51 ;;
|
|
|
52 ;; Modified 29-nov-94 by Ben Wing <wing@spg.amdahl.com>: small fixes
|
|
|
53 ;; that should hopefully make things work under HPUX and IRIX.;
|
|
|
54 ;;
|
|
|
55 ;; Modified 15-jul-95 by Dale Atems <atems@physics.wayne.edu>:
|
|
|
56 ;; some extensive rewriting to make things work right (more or less)
|
|
|
57 ;; under IRIX.
