This tries to add information about when each option was added. It goes
back to version 183.
The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.
* sd-bus/man: document EBUSY error in bus_message_read
The EBUSY error can be returned from sd_bus_exit_container(), and, if
that happens, it will be propogated upwards towards bus_message_read. In
terms of documentation, this means that bus_message_read's man page
can't just include the error text for sd_bus_message_read_basic, as
reading basic types exclusively doesn't have the potential for this
error.
sd_bus_message_read_basic's error documentation isn't incorrect when
applied to sd_bus_message_read, it's just incomplete. While EBUSY is
documented in sd_bus_message_open_container.xml,
it's explanation is unique to the sd_bus_message_exit_container function
and makes for poor documentation of the general read API.
Logically, this is better, because we're describing a subset of possible
return values. Visually this also looks quite good because groff renders
refsect2 much less prominently.
Also rewrap things, add <constant> in various places, fix some typos.
The "include" files had type "book" for some raeason. I don't think this
is meaningful. Let's just use the same everywhere.
$ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml
No need to waste space, and uniformity is good.
