Once you have the tar.gz file on the central machine you should be able to create the HTML report. Unfortunately I could not find a nice way to do it but with the help of Ash Berlin and Steve Purkis we came up with workaround:

First unzip the file using

tar xzf tap.tar.gz

Then you can run the following command:

prove --exec 'cat' -Q --formatter=TAP::Formatter::HTML t/ > output.html

This will only work on Unix, maybe on Windows one can replace 'cat' with 'type' but I have not tried it. In any case I hope soon there will a better solution to this.

prove --exec 'cat' -Q --formatter=TAP::Formatter::HTML t/ > output.html
