bug#23304: import pypi: Option o keep the downloaded file

Hi,

when importing packages from pypi I often need to look at the source.
Either for checking the license, getting a better description, find out
how tests are run or which build system to use.

For this I'd appreciate an option to keep the downloaded archive (or
even better keep the unpacked archive) for easy access. This option
could be called `-K, --keep-downloads=DESTDIR`, where DESTDIR is the
destination directory where to download (or unpack) the archive.

Maybe this option should be available for all `imports` as it may be
useful there, too.

Some kind of :-)

1) From a usability point of view, this should be part of "guix import"
since this is what the user does and where she is looking for help.

2) "guix build --source" returns a derivation, whereas "guix import"
ought to return the original, unchanged source. (One could argue that on
"import", the derivation is the unchanged source depending on nothing)

3) Of course one could use the output of "guix import", pass it to "guix
build --source" and get the original source. But
a) this would download the source twice
b) would intermix phases: the package definition is in early draft, but
"build" should return the source. This does not match.

4) In any case, "guix import" should display the name of the downloaded
archive.

bug#23304: import pypi: Option o keep the downloaded file

Hi

Is this really needed? I look at the webpages when importing stuff.

For npm Julien and I created a special tool to do the job of fetching
the dependencies. 

You could easily roll-your-own and change (call-with-temporary-output...
-> (call-with-output-file ...)

As it is only Hartmut who asked for this during 2 years of everyone
using the importer I vote for closing this as "won't fix".
