Indeed it is only the first step.

The purpose of putting scripts on installer.pbwiki.com is so that those
scripts can be loaded into 'any' image with the minimum of Installer or
at best LPF loaded. This scenario is intended to enable the user to see
and select what to apply to their own images. Its a place to easily try
out and publish sets of fixes, temporarily, in lieu of a more formal
process which will need more than just Installer/LPF.

This is not the same as the more controlled formal process of building
the next (3.11) release. For details of this more formal process...

If you load into a 3.10 image...

Installer install: 'Tasks'.

You will find classes ReleaseAfterSqueak310 and
ReleaseAfterSqueak310Unstable, the method #taskBugFixes has your bug
fixes, as migrated from the original harvested
installer.pbwiki.com/MinorFixesUnstable-Squeak3:10 page. You can now
contribute your fixes to this package in repository:
http://www.squeaksource.com/Tasks package: Tasks-Squeak3.10"

To build a 3.11u (unstable test candidate) for yourself run the
following command line...

.../vm/squeak /Squeak/pr_next/Squeak3dot10.7159.image
http://installer.pbwiki.com/f/LPF.st Installer
do="NextUnstableCandidate" SmalltalkImage save=Squeak3.11u2

This will soon be included in our automated build and testing tool
"Bob", but for now you can give it a go. It's not quite there yet since
the script doesnt run to completion as yet but you should get the
general idea. As the script runs, the mantis reports for every fix
loaded are collated and added to the instance side of
ReleaseAfterSqueak310Unstable as documentation.

best regards

Keith
