[bug#30274] [PATCH 00/21] gnu: Add licensecheck (license checker for source files).

[Oleg Pykhalov <go.wigust@gmail.com>]

Hello Guix,

Licensecheck attempts to determine the license that applies to each file
passed to it, by searching the start of the file for text belonging to various
licenses.


Some notes while I've adopted `guix import cpan` produced packages:

- perl-b-hooks-op-check, perl-bareword-filehandles, perl-multidimensional had
  a perl-gtk-perl in native-inputs.

- perl-test-roo had a perl-bareword-filehandles in native-inputs.


An example of running licensecheck
