checkfile
Lsb files are rpm's with a lsb- prefix, that depend on a package called 'lsb' and nothing else.
scan
Uses the parent scan method to read the file. lsb is added to the depends.
prep
The parent's prep method is used to generate the spec file. First though, the package's name is
munged to make it lsb compliant (sorta) and lsb is added to its dependencies.
revert
Undo the changes made by prep.
build
Uses the parent's build method. If a lsb-rpmbuild is available, uses it to build the package.
incrementrelease
LSB package versions are not changed.
