Re: [Swarm-Support] MacOS X Binaries Update

[Bill Northcott]

Thanks for the contribution.

I am not sure it is appropriate for a ReadMe but it would make a very good 
web page.

A couple of comments:
MacOS X is really NOT FreeBSD at the core.  The kernel is Mach-O and the 
Cocoa/Carbon gui stuff is built on that.  Also built on the same core are 
a large set of FreeBSD commands and libraries.  They are almost orthoganal 
to the main GUI system.  Until Jaguar, they were even an optional intall 
and virtually all mainstream Apps like MS Offce, Netscape, etc would run 
perfectly well with them removed.  Apple includes this layer to make it 
easy to get opensource stuff to work, and to get the compiler to build 
which is rather important!

Good point about the X11 SDK that should be in the ReadMe.

The purpose of some of the software libraries is:
BLT - Graphical widget set including graph drawing and other good stuff.
Tk required to support BLT
Tcl required to support Tk

GNU sed, an enhanced version of BSD sed, is required by gnu libtool (not 
to be confused with the completely different MacOS X libtool)  which is 
the current build system.
