14.5.1. Why should I use CTM?

CTM will give you a local copy of the ``FreeBSD-current'' sources. If you are an active developer on FreeBSD, but have lousy or non-existent TCP/IP connectivity, CTM was made for you. You will need to transfer up to four deltas per day (or you can have them arrive in email automatically), the sizes for which are always kept as small as possible. This is typically less than 5K, with the occasional (one in ten) being 10-50K and every now and then a biggie of 100K+ or more coming around.

You will also need to make yourself aware of the various caveats in running ``current'' sources, and for this it is recommended that you read Staying current with FreeBSD .
