+The olpc-os-builder machinery has been used successfully with systems running '''Fedora 11 i386''' through '''Fedora 13 x86_64'''. What the host system runs shouldn't matter much, because all the work is being done in a chroot environment, but olpc-os-builder is known to fail on Ubuntu due to a missing dependency.

+== Building custom RPMs ==
+* Go to the <tt>rpms/PACKAGENAME</tt> in the dextrose tree
+* Edit the spec file (remember to bump the revision)
+* <tt>make i586</tt>
+* Wait for rpmbuild to do its job
+* Now upload this rpm to a yum repository and add it to the ini file used by the OLPC OS builder.
+* To automate this step, we have a rule <tt>make uploadrpm</tt> which points at the Dextrose repository.
+Edit <tt>rpms/common/Makefile.common</tt> or <tt>rpms/common/uploadrpm</tt> to retarget this rule to your
