Core API's

libRD11:

The C language API.
CVS: Module: MMRA/libRD11
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/MMRA/libRD11
Header: /local/mrl/include/RD11.h
Linkable: /local/mrl/lib/Robodaemon/libRD11.[a,so]
Man Page: /local/mrl/man/man3/libRD11.3 online
Test source: Dependencies: libSocketUtilities (see below)
Comments:

libRD11++:

The C++ language API.
CVS: Module: MMRA/libRD11++
Header: /local/mrl/include/RD11++.h
Linkable: /local/mrl/lib/Robodaemon/libRD11++.[a,so]
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/MMRA/libRD11++ (files are in Attic until the Stable branch is merged)
Man Page: None
Test source: In the libRD11++ CVS module (testrd11++).
Dependencies: libsocket++ (see below), STL
Comments:

JRD10:

Java-based classes for RD10. In theory, they should be fully compatible with RD11.
CVS: Module: JRD10
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/JRD10
Web Docs: There are docs in CVS.
Test source: There is possibly some in the CVS module.
Dependencies: None
Comments:

RD11.pm

A perl module for RD11.
CVS: MMRA/etc/RD11.pm
Docs: The perl module contains perldoc tags. In theory, Eric once installed the documentation somewhere, but I don't know where.
Dependencies: None.
Comments: I have eviscerated this module many times over and customize it to my own needs:
simra@Wind:[etc] 59>find ~ -name RD11.pm
/home/discovery/simra/MMRA/etc/RD11.pm
/home/discovery/simra/mrl/RD11.pm
/home/discovery/simra/Localize/data/mrl-windows/RD11.pm
/home/discovery/simra/Localize/data/simul-explore/RD11.pm
It would be worth finding the one with the latest revision date, cleaning it up (it emits all kinds of rude debugging messages) and putting it somewhere central (like CVS).

Other Libraries:

libSocketUtilities

A large beast for handling sockets.
CVS: Module: MMRA/libSocketUtilities
Header: /local/mrl/include/SocketUtilities.h
Linkable: /local/mrl/lib/Robodaemon/libSocketUtilities.[a,so]
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/MMRA/libSocketUtilities
Man Page: Several in /local/mrl/man/man3 Test source: None that I'm aware of, although there are many sample programs like testRD11 that are dependent on it indirectly
Dependencies: None
Comments: I have never learned to completely trust it, although I depend on it heavily, both inside daemon and in many other programs.

libsocket++

A third-party c++ socket stream class. There are multiple versions online, but this one is the most linux-friendly I could find. I have dogged the authors to create a SourceForge site for it, but have yet to see any action.
CVS: Module: socket++
Header: /local/mrl/include/sockinet.h
Linkable: /local/mrl/lib/libsocket++.a
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/socket++
Docs: Try /local/mrl/info
Test source: In the CVS source.
Dependencies: None
Comments: Reliable for simple apps. It has not been put through any serious testing otherwise.

libmrl++

An assortment of useful c++ classes. This has nothing to do with Daemon, but I'd like to promote its use. CVS: Module: mrl++
Header: /local/mrl/include/mrl++.h
Linkable: /local/mrl/lib/libmrl++.[a,so]
WebCVS: http://www.cim.mcgill.ca/~mrl/cvsweb/cvsweb.cgi/mrl++
Docs: There is a(n outdated) README in the CVS source
Test source: None.
Dependencies: None
Comments: More documents are needed.
