Some notes for anyone maintaining / developing gmysql:

The "original" source is in gmysql_<ver>.tar.gz, i.e. the tarball part of a
debian source package. This *doesn't* contain any generated files, such as
configure, Makefile.in, etc. You need autoconf and automake to work with this
(the debian source control file specifies these as a build dependency). Files
such as "missing" and "install-sh" and not supplied, they are added by the call
to automake in debian/rules. To build from this archive, either use the debian
source package build tools, or run:

$ aclocal
$ automake --add-missing
$ autoconf
# then run configure as normal

Running "debian/rules dist" or "debian/rules distcheck" will generate a
gmysql-<ver>.tar.gz (note the '-' instead of a '_') archive suitable for
distribution. This will include everything in the debian source package
(because we always want the user to have the full source), and it will not
depend on autoconf or automake.
