# This is the makefile for generating the message catalog file and
# building lang.mo files from the translated lang.po catalogs.
# This makefile may be invoked to build either audacity.pot or any lang.mo

# because we are in a subdirectory setting DESTDIR to a relative path doesn't
# work - it gets interpreted relative to the locale directory in the source
# tree. This is because relative DESTDIRs aren't supported. It could be worked
# around by something along the lines of
#  if (DESTDIR is relative)
#  	DESTDIR=$top_srcdir/DESTDIR
#  fi
#  but I can't see how to implement this. So for the moment stick to absolute
#  paths in DESTDIR
