 # The toplevel "clean" targets are generated from Makefile.am, not this file.

 # The main purpose of this GNUmakefile is that its targets can be invoked
 # without having to call autogen.sh and configure first. That means automake
 # variables may or may not be defined. Here, we use the current working
 # directory if a relevant variable hasn't been defined.
 #
 # The idea is to keep generated artifacts in the build tree, in case a VPATH
 # build is in use, but in practice it would be difficult to make the targets
 # here usable from a different location than the source tree.
