=item lsb
To convert from lsb packages, the Red Hat Package Manager must be installed.
Unlike the other package formats, alien can handle the depenendencies of
lsb packages if the destination package format supports dependencies. Note
that this means that the package generated from a lsb package will depend on
a package named "lsb" -- your distribution should provide a package by that
name, if it is lsb compliant. The scripts in the lsb package will be converted
by default as well.
To generate lsb packages, the Red Hat Package Manager must be installed,
and alien will use by preference a program named lsb-rpm, if it exists.
No guarantees are made that the generated lsb packages will be fully LSB
compliant, and it's rather unlikely they will unless you build them in the
lsbdev environment.
