I was about to update the JCAS, JCA and CAJ links to all point to the
GitHub jca project, although I would rather point to a page that has
links to online documentation and more information about how to use the
libraries. Didn't there used to be some API documentation about the JCA
library API? Is the Javadoc published anywhere?

However, I see that both the extensions index page and the page at
http://epics-jca.sourceforge.net/ list JCA as being the client library
that used JNI to wrap the C++ client library, while CAJ was the name
given to the pure Java implementation of the library, so it seems that
we have switched our names around recently. The maintainers agreed to
abandon the JNI-based code which was supposed to be archived under the
epics-rip project, and all future maintenance will occur on the pure
Java code.

However I can't actually find any C code in the epics-rip/caj project,
which actually contains the code for JCAS, Matej's pure-java CA server
implementation and not the JNI-based client library implementation at
all. I just filed an issue against the epics-rip/caj project about this.

Until all this naming gets cleared up I am reluctant to confuse people
further by changing any links.

Done, but since there is PCAS API reference documentation linked from
that page we need to decide what to do about those documents; at minimum
the README.md should also point to the above page (the CA reference
manual which is linked only covers the CA client API).
