10 | =head1 NAME | |
11 | ||
12 | installhtml - converts a collection of POD pages to HTML format. | |
13 | ||
14 | =head1 SYNOPSIS | |
15 | ||
16 | installhtml [--help] [--podpath=<name>:...:<name>] [--podroot=<name>] | |
17 | [--htmldir=<name>] [--htmlroot=<name>] [--norecurse] [--recurse] | |

21 | =head1 DESCRIPTION | |
22 | ||
23 | I<installhtml> converts a collection of POD pages to a corresponding | |
24 | collection of HTML pages. This is primarily used to convert the pod | |
25 | pages found in the perl distribution. | |
26 | ||
27 | =head1 OPTIONS | |
28 | ||
29 | =over 4 | |
30 | ||
31 | =item B<--help> help | |
32 | ||
33 | Displays the usage. | |
34 | ||
35 | =item B<--podpath> POD search path | |
36 | ||
e05c04ea | 37 | The list of directories to search for .pod and .pm files to be converted. |
54310121 | 38 | Default is `podroot/.'. |
39 | ||
40 | =item B<--podroot> POD search path base directory | |
41 | ||
42 | The base directory to search for all .pod and .pm files to be converted. | |
43 | Default is current directory. | |
44 | ||
45 | =item B<--htmldir> HTML destination directory | |
46 | ||
47 | The base directory which all HTML files will be written to. This should | |
48 | be a path relative to the filesystem, not the resulting URL. | |
49 | ||
50 | =item B<--htmlroot> URL base directory | |
51 | ||
52 | The base directory which all resulting HTML files will be visible at in | |
53 | a URL. The default is `/'. | |
54 | ||
55 | =item B<--recurse> recurse on subdirectories | |
56 | ||
57 | Whether or not to convert all .pm and .pod files found in subdirectories | |
58 | too. Default is to not recurse. | |
59 | ||
60 | =item B<--splithead> POD files to split on =head directive | |
61 | ||
e05c04ea | 62 | Colon-separated list of pod files to split by the =head directive. These |
54310121 | 63 | files should have names specified relative to podroot. |
64 | ||
65 | =item B<--splititem> POD files to split on =item directive | |
66 | ||
e05c04ea | 67 | Colon-separated list of all pod files to split by the =item directive. |
54310121 | 68 | I<installhtml> does not do the actual split, rather it invokes I<splitpod> |
69 | to do the dirty work. As with --splithead, these files should have names | |
70 | specified relative to podroot. | |
71 | ||
72 | =item B<--libpods> library PODs for LE<lt>E<gt> links | |
73 | ||
e05c04ea | 74 | Colon-separated list of "library" pod files. This is the same list that |
54310121 | 75 | will be passed to pod2html when any pod is converted. |
76 | ||
77 | =item B<--verbose> verbose output | |
78 | ||
79 | Self-explanatory. | |
80 | ||
81 | =back | |
82 | ||
83 | =head1 EXAMPLE | |
84 | ||
85 | The following command-line is an example of the one we use to convert | |
86 | perl documentation: | |
87 | ||
88 | ./installhtml --podpath=lib:ext:pod:vms \ | |

93 | --splititem=pod/perlfunc \ | |
94 | --libpods=perlfunc:perlguts:perlvar:perlrun:perlop \ | |
95 | --recurse \ | |

113 | --podpath - colon-separated list of directories containing .pod and | |
114 | .pm files to be converted (. by default). | |
115 | --podroot - filesystem base directory from which all relative paths in | |
116 | podpath stem (default is .). | |
117 | --htmldir - directory to store resulting html files in relative | |
118 | to the filesystem (\$podroot/html by default). | |
119 | --htmlroot - http-server base directory from which all relative paths | |
120 | in podpath stem (default is /). | |
121 | --libpods - comma-separated list of files to search for =item pod | |
122 | directives in as targets of C<> and implicit links (empty | |
123 | by default). | |
124 | --norecurse - don't recurse on those subdirectories listed in podpath. | |
125 | (default behavior). | |
126 | --recurse - recurse on those subdirectories listed in podpath | |
127 | --splithead - comma-separated list of .pod or .pm files to split. will | |
e05c04ea | 128 | split each file into several smaller files at every occurrence |
54310121 | 129 | of a pod =head[1-6] directive. |
130 | --splititem - comma-separated list of .pod or .pm files to split using | |
131 | splitpod. | |
132 | --splitpod - where the program splitpod can be found (\$podroot/pod by | |
133 | default). | |
134 | --verbose - self-explanatory. | |
