  some observations about the documentation (or lack thereof) of this
task since tim seemed susprised about it, and i remember vaguely
running across it once upon a time but forgetting about it.

  the entirety of mention of populate_sdk in all of the checked out
yocto-docs repo is:

$ grep -rw populate_sdk *
documentation/ref-manual/eclipse/html/poky-ref-manual/ref-variables-glos.html:                <code class="filename">bitbake -c populate_sdk imagename</code>).
documentation/ref-manual/ref-variables.xml:                <filename>bitbake -c populate_sdk imagename</filename>).
documentation/ref-manual/ref-classes.xml:        populate_sdk*.bbclass
$

and part of that is a large comment at the end of ref-classes.xml
listing all of the undocumented classes, so it would seem this task
merits a bit more coverage.

  also, the yocto wiki currently contains this page for the "SDK
Generator" but it hasn't been updated since 2010:

https://wiki.yoctoproject.org/wiki/SDK_Generator

  just making some observations, i'm currently working through the ADT
manual and building an SDK for my beagle as we speak.
