[dm-devel] What license is multipath-tools under

Thanks Xose, for digging this information. But shouldn't this information go
into respective source files?

Recently, at Debconf, I came aware of Fossology [1]. It is a compliance tool for
license, copyright and export control scans. I have spawned off a job [2] and am
curious of the result. But looks like their server may be having a problem at
the moment.

But it is standard practise in most Free Software projects to define the
licensing proper. And for a project with mixed licenses, it'd be best to have
individual source files mention their license.
