Refactor the settings of $docdir
This is a completely noop change for this project, since before this commit nothing was using $docdir nor PROGRAM_TARNAME.
Setting the fourth parameter of AC_INIT() makes it set PROGRAM_TARNAME,
which then used as the last path component of the default docdir,
effectively making $docdir be the same as the previous
BASE_DIR/
DOC_MODULE.
I've done this while looking to make the docs installation properly work (coming MRs).
In this way, the standard --docdir
flag of autoconf can work again, and that --with-html-subdir
also becomes more useful (since passing an empty string would have forced /html if one didn't want it, for example).
Probably I should have continued and dropped the whole --with-html=
and --with-html-subdir=
parameter support since autoconf already has a default --htmldir
, but I didn't bother at this time.
