# curl man page generator
|
||
|
|
|
||
|
|
This is the curl man page generator. It generates a single nroff man page
|
||
|
|
output from the set of sources files in this directory.
|
||
|
|
|
||
|
|
There is one source file for each supported command line option. The output
|
||
|
|
gets `page-header` prepended and `page-footer` appended. The format is
|
||
|
|
described below.
|
||
|
|
|
||
|
|
## Option files
|
||
|
|
|
||
|
|
Each command line option is described in a file named `<long name>.d`, where
|
||
|
|
option name is written without any prefixing dashes. Like the file name for
|
||
|
|
the -v, --verbose option is named `verbose.d`.
|
||
|
|
|
||
|
|
Each file has a set of meta-data and a body of text.
|
||
|
|
|
||
|
|
### Meta-data

||
|
|

|

### Body
|
||
|
|
|
||
|
|
The body of the description. Only refer to options with their long form option
|
||
|
|
version, like `--verbose`. The output generator replaces such option with the
|
||
|
|
correct markup that shows both short and long version.
|
||
|
|
|
||
|
|
Text written within `*asterisks*` is shown using italics. Text within two
|
||
|
|
`**asterisks**` is shown using bold.
|
||
|
|
|
||
|
|
Text that is prefixed with a space is treated like an "example" and gets
|
||
|
|
output in monospace.
|
||
|
|
|
||
|
|
## Header and footer
|
||
|
|
|
||
|
|
`page-header` is the file that is output before the generated options output
|
||
|
|
for the master man page.
|
||
|
|
|
||
|
|
`page-footer` is appended after all the individual options.
|
||
|
|
|
||
|
|
## Generate
|
||
|
|
|
||
|
|
`./gen.pl mainpage`
|
||
|
|
|
||
|
|
This command outputs a single huge nroff file, meant to become `curl.1`. The
|
||
|
|
full curl man page.
|
||
|
|
|
||
|
|
`./gen.pl listhelp`
|
||
|

|
||
|

Generates a full `curl --help` output for all known command line options.
