build-localtest.pl - Create a t/localtest.data file from test output.
perl tools/build-localtest.pl <test_output >t/localtest.data
This almost doesn't deserve to be a script. It simply reads standard input looking for things of the form "t/spec/*/*.(t|rakudo)", then prints those to the standard output. Typically I simply run the script, then copy-and-paste the summary results of a test run into the window and capture the results to t/localtest.data .
