Edit File: README

These config.sh.* files are generated during the package build
and installed into the libperl5.xx package, in the directory
/usr/lib/<triplet>/perl/config-data-<version>. They contain probed values
about system configuration, used for cross building the package.

The probes currently need to run on the native architecture, so they
cannot be used for cross building. As a workaround, we store the results
in the built binary package and then manually copy them back to the
source package as needed.

The process is currently experimental, and no commitment is made on long
term feasibility of this. We will see how it goes.

For more information, see the thread starting at
 http://lists.alioth.debian.org/pipermail/perl-maintainers/2016-January/005241.html

There is some tooling to help the process of incorporating the generated
config.sh.* files from architecture specific binary packages back into
the source package:

- debian/cross/download-deb can be used to pull in the required binary package

- debian/cross/extract-config-sh can then be run on the downloaded
  package(s) to copy the config.sh.* files into the source tree and commit
  the changes into the git repository.

An example transcript would be:

$ for arch in amd64 arm64 armel armhf i386 mips64el mipsel ppc64 s390x; do ./debian/cross/download-deb -p libperl5.32 -v 5.32.1-2 -s 'deb http://deb.debian.org/debian unstable main' $arch; done
$ for arch in alpha hppa hurd-i386 ia64 m68k powerpc ppc64 riscv64 sh4 sparc64 x32; do ./debian/cross/download-deb -p libperl5.32 -v 5.32.1-2 -s 'deb http://deb.debian.org/debian-ports unstable main' $arch; done
$ ./debian/cross/extract-config-sh libperl*.deb

The debian-ports part needs the debian-ports-archive-keyring package installed
(but could be done in an ephemeral chroot if that seems preferrable.)

As always, this is still work in progress and will hopefully improve over time.
