One for tarball-only, the other to be updated any time we get a new value of $(VERSION). * Makefile.am (dist-hook): Create .tarball-version in dist tarball. * GNUmakefile (_curr-ver): Make git-version-gen use it. * .gitignore: Ignore it.

# generated rules created via Makefile.maint as well as Makefile.maint itself.
|
|
# This makefile is used only if you run GNU Make.
|

# It is necessary if you want to build targets usually of interest
