From: felipensp@gmail.com (Felipe Pena)

Hi Zoe,

great work on this new run-tests! :D

I was testing it and noticed a problem when running using the following com=
mand:
$ ~/dev/php5_4/sapi/cli/php run-tests.php  -z 8 -p
~/dev/php5_4/sapi/cli/php ~/dev/php5_4/

It shows the PHP messages:
[...]

/home/felipe/dev/phpruntests/src/testcase/sections/configurationsections/rt=
GzipPostSection.php
