13 * man2html will add links to the converted manpages. The function add_links
14 * is used for that. At the moment it will add links as follows, where
15 * indicates what should match to start with:
16 * ^^^
17 * Recognition Item Link
18 * ----------------------------------------------------------
19 * name(*) Manpage ../man?/name.*
20 * ^
21 * name@hostname Email address mailto:name@hostname
22 * ^
23 * method://string URL method://string
24 * ^^^
25 * www.host.name WWW server http://www.host.name
26 * ^^^^
27 * ftp.host.name FTP server ftp://ftp.host.name
28 * ^^^^
29 * <file.h> Include file file:/usr/include/file.h
30 * ^^^
31 *
32 * Since man2html does not check if manpages, hosts or email addresses exist,
33 * some links might not work. For manpages, some extra checks are performed
34 * to make sure not every () pair creates a link. Also out of date pages
35 * might point to incorrect places.
36 *
37 * The program will not allow users to get system specific files, such as
38 * /etc/passwd. It will check that "man" is part of the specified file and
39 * that "/../" isn't. Even if someone manages to get such file, man2html will
40 * handle it like a manpage and will usually not produce any output (or crash).
41 *
42 * If you find any bugs when normal manpages are converted, please report
43 * them to me (rcb5@win.tue.nl) after you have checked that man(1) can handle
44 * the manpage correct.
45 *
46 * Known bugs and missing features:
47 *
48 * * Equations are not converted at all.
49 * * Tables are converted but some features are not possible in html.
50 * * The tabbing environment is converted by counting characters and adding
51 * spaces. This might go wrong (outside <PRE>)
52 * * Some pages look better if man2html works in troff mode, especially pages
53 * with tables. You can decide at compile time which made you want to use.
54 *
55 * -DNROFF=0 troff mode
56 * -DNROFF=1 nroff mode (default)
57 *
58 * if you install both modes, you should compile with the correct CGIBASE.
59 * * Some manpages rely on the fact that troff/nroff is used to convert
60 * them and use features which are not descripted in the man manpages.
61 * (definitions, calculations, conditionals, requests). I can't guarantee
62 * that all these features work on all manpages. (I didn't have the
63 * time to look through all the available manpages.)
