po4a-translate; "po4a-translate is deprecated.  The unified po4a(1) program is
more convenient and less error prone."
(PO4A_PARAMS): Remove the Texinfo format option.  This option is specified in
the configuration file (po/doc/po4a.cfg).

the po4a-updatepo program.  The PO4A defined here can be used in
Makefiles (e.g. po/doc/local.mk below).  The po4a command integrates the
functionality of po4a-updatepo and is currently recommended for use [1].  The
po4a-updatepo command has been replaced by the po4a command and are not used
from anywhere.
* po/doc/local.mk (%D%/%.pot): Use a po4a command instead of the po4a-updatepo
for the POT generation.  This eliminates the warning of po4a-updatepo;
"po4a-updatepo is deprecated.  The unified po4a(1) program is more convenient
and less error prone."  Here, the file paths are passed using variables.  This
is because the po4a command needs to be executed for each language and each
file.  Dummy values are passed for those that are not needed to update the POT
file.
* po/doc/po4a.cfg: Add a po4a config file for the POT generation.  The po4a
command requires a configulation file.
