+changes to a source tree available on a regular basis by email.
 This is a good way to stay up to date with the current source tree or
 CVS repository if you have a slow Internet connection, for instance via modem.
 
 <P>
+OpenBSD CTM distributes all modules of the OpenBSD CVS repository
+plus checked out versions of several of theses modules.
 CTM uses very low bandwidth for distributing the changes to the tree,
 and compresses them using <tt><b>gzip -9</b></tt>.  In contrast to
 <a href="cvsup.html">CVSup</a>, CTM is written in plain C language
 and therefore available for every platform supported by OpenBSD.
+CTM implements a so called push system, while all other methods to
+get access to the OpenBSD CVS repository are pull systems.
