The recutils output is not the *only* way to access the package data= .
All packages in Guix are just Scheme variables.=C2=A0 Package data are
available as S-expressions and can be read by Scheme programs or parsed
by external applications.=C2=A0 The recutils output is just an additional format used when interacting with Guix on the command line.

(Personally, I=E2=80=99m not enthusiastic about adding a serialised form of= the
source field to the recutils output.)

~~ Ricardo



Not s= o long ago, someone posted a script that produced a web page with the resul= ts of linting all the packages

That= 's an example

One could produce= an xml file to be imported in Gephi, just to make another example.

=
Or a SQL text file to be imported in some = relational db, or a different format to be imported in some not relational = db...
