* LSB package support. It can generate LSB packages (not guarenteed

Browse Source 
fully conformant with the LSB), and it can take LSB packages and convert
     them into other formats. Unlike all the other conversions, lsb packages's
     dependancy (on lsb) and their package scripts are preserved in the
     generated packages (when allowed by the target package format). This means
     your distribution will need to have a package named 'lsb' for the result
     to be installable. (Debian will have one soon..)
   * Suggest rpm-lsb, which is the preferred rpm to build lsb packages with.
     Use it if it's present, plain old rpm otherwise.

This is an object class that represents a lsb package. It is derived from
Alien::Package::Rpm.

Lsb files are rpm's with a lsb- prefix, that depend on a package called 'lsb'
and nothing else.

Uses the parent scan method to read the file. lsb is added to the depends.

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.

Uses the parent's build command. If a lsb-rpm is available, uses it to build
the package.
