Log:
Add Skelton "varnishtest" program.
This is a test-driver which will be able to drive low-level tests of
varnish functionalty.
The present code manages to parse the example testcase description,
more work to follow.
XXX: needs to be auto*'ed, right now it uses FreeBSD makefile syntax.
Added: trunk/varnish-cache/bin/varnishtest/Makefile
