I will add this to the links page on the lprof web site. Thanks for updating
this.
One comment about the content. While apps like kgamma and tkgamma will allow
users to adjust the monitor gamma the chart used by these is one that is not
particularly repeatable or consistant in actual use. An app named monica
uses the Norman Koren gamma chart which is the same one used in lprof. This
chart is much better than those used in most gamma setting apps and Norman
claims that it allows for the gamma to be consistently set with a tolerance
+-0.1. My experience is that this is a very conservative claim and I think
that the actual tolerance is closer to +-0.05. I highly recommend monica as
the best app for this function.

A better link for this stuff is:

This page belongs to one of the current lprof developers.

Lprof now has a volunteer who is working on the Windows port. I had already
done a significant amount of Windows porting work on 1.11.0 and other work
since that time has been very careful about keeping the code base portable.
But I am not a Windows person and I thought that someone who was would do it
more justice. It took a while to find a volunteer but Joe Pizzi stepped
forward about a week ago and is highly qualified. He now has the Windows
port of the current CVS code to the point where it builds and runs. His
changes have also been regression tested on Linux. This still needs more
testing and I suspect some fixes before it is released. It will also be
necessary to package it into an installer.
The current plan is to release the Windows binary along with the next source
tarball as version 1.11.4 some time in the next few weeks. By the way
current CVS is internationalized (as will the next release) and we are
looking for volunteers to do translations for the GUI. If you are interested
in volunteering please contact me. I would like to have at least a handful
of good translations before the next release. Right now the only one that is
even close is the Russian translation which is also the only one where
someone has volunteered to do the work.
