Subject: autopkgtests: Add machinery for regenerating test cases
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=chiark-tcl.git;a=commitdiff_plain;h=e275d3b522764c2c98797207a50d24a6534cbe83

autopkgtests: Add machinery for regenerating test cases

Sadlythe dependencies are not in the *.deb because we are a
portmanteau package, so we must put the actual shlib dependencies in
debian/tests/control.  This involves running dpkg-shlibdeps etc.

The plan is to do this occasionally and commit the result to git.
