This simplifies help2doc since it now just have to do one single thing with
output of either --config-help or --long-help. The new manpage is not as
fancy wrt. indentation and sub titles but it is more uniform and we get a
HTML version.
Generate options-{config,command}.txt with help2doc. Only conditionally
check for API header files, to speed up execusion.
You can now use: make {all-docs,pdf,html,man,api,update-man}
instead of: make {all-docs,pdf-docs,html-docs,man-docs}
Away is building into separate dirs. This makes make able to actually get
dependencies right, since there are now a collection of 'common' build
rules, some of which have even been moved to use the cmd infrastructure.
To update the man pages there is a new update-man rule. It builds the
manual pages and copies them to their proper place under man/ while doing
the final preformatting.
As good thing is that the (two) man pages are moved to .txt files and
include the generated content.
The API building thing is also refined. It builds into api/ and builds it's
list of files dynamically by searching throught the .h files in the src/
directory. Documented header files must contain a comment like this:
/* API Doc :: <api-name> */
where <api-name> is the name used for the file under api/, for example
dom-scanner.
