## spec2deb ##

This utility takes a rpm package.spec as input generating a series of
debian-specific files like the package.dsc build descriptor and the
debian.diff.gz / debian.tar.gz containing the control file and patches.

The result is a directory that is ready for dpkg-source to build a *.deb.

Note that the script has some builting "magic" to transform the rpm spec
%build and %install scripts as well. Although it works in a lot of cases
it might be failing in your case. And yes ... we take patches.

## debtransform ##

The script is mainly used in converting existing rpm packages in the
Opensuse Build System (OBS). That system has a special "debtransform"
script that can take an existing tarball from the existing rpm sources
repository tree (without renaming it to some "*.orig.tar.gz" name) to
populate a debian source directory. The "debtransform" script will also
generate the debian.diff.gz which would be otherwise done by this
spec2deb script. In the "--debtransform" mode however the spec2deb
script will create a "debian.tar.gz" that will be picked up OBS's
"debtransform" script. The resulting temporary debian source directory
for Debian/Ubuntu builds will therefore mainly contain specs and code
generated by "spec2deb".

Note that the "spec2deb" script will automatically switch into the
"--debtransform" mode when an ".osc" subdirectory is found which flags
the current directory to be a checkout from some OBS project/package.

## debian.diff.gz ##

In the "--no-debtransform" mode the script will prefer to generate a
package.debian.diff.gz which is much easier to read. It does have the
same content however as the debian.tar.gz including the required files
like debian/source/format, debian/control, debian/changelog and the
debian/patches.

For debugging purposes the script has additional options that will
show only one of these generated elements. While many things can be
converted directly you should take care to check the "--debian-rules"
generated from the rpm build script parts.
