  http://docs.openlayers.org/library/deploying.html#custom-build-profiles

"Once you have included these files, you should add more files to the
‘[include]’ section of the file. The files listed here should be the list of
files containing any class you use in your application. You can typically find
these classes by looking through your code for any cases where ‘new
OpenLayers.ClassName()’ is used."

The documentation tells you how to cater your build to your application.
Anyone experienced enough to write an OpenLayers app should be able to
build their own customized build profile by reading the documentation; if
you feel that is not the case, a change in the wording or a suggestion as
to how that documentation could be improved is welcome.
