13.5.4 AM_PO_SUBDIRS in po.m4

The AM_PO_SUBDIRS macro prepares the po/ directories of the package for building. This macro should be used in internationalized programs written in other programming languages than C, C++, Objective C, for example sh, Python, Lisp. See Programming Languages for a list of programming languages that support localization through PO files.

The AM_PO_SUBDIRS macro determines whether internationalization should be used. If so, it sets the USE_NLS variable to ‘yes’, otherwise to ‘no’. It also determines the right values for Makefile variables in each po/ directory.
