Commit Message

Karel Zak Dec. 12, 2014, 12:35 p.m. UTC 
Add ./autogen.sh script, you have to use it after "git clone/clean" to
generate ./configure from configure.ac.

Modify version.sh to be usable from the configure script.

The patch also renames Makefile to Makefile.in, but does NOT change
anything in the file.
