This package was built from a "_orig.tar.gz" tarball that had all
Autotools-generated files removed from the upstream tarball.  This
was done using the "orig" target that is defined in "Makefile.am",
which is part of the original upstream source package.

The package is built using autoreconf, so all of those removed
files are re-created upon building.  Removing those files helps
porting to new architectures and ensures building with the latest
versions of all Autotools programs.

By default, Autotools will convert a lex/flex ".l" file into a ".c"
file, and leave the .c file in place during "make clean" or
"make distclean".  Therefore, debian/clean removes the generated
".c" files in the src directory.
