-You can build just the engine (and avoid all the gtk/libxml/etc dependancies)
-by doing the same in the src/engine directory.

+different ways (standalone engine with seperate clients, build engine only,

If you have GCC4, it is HIGHLY recommended that you enable your SIMD

-with SSE) through your CXXFLAGS environment variable. The performance
-improvement (and denormal avoidance if you have a P4) is significant.

Om makes very heavy use of assertions to catch bugs. Assertions have a
-performance hit unless the preprocessor symbol NDEBUG is defined. By default
-the configure script will add this to the end of your flags, but it's worth
-noting. You really don't want assertions turned on in a production build.

-idea to rebuild with --enable-debug, chances are you'll hit an assertion and
-the console output will be a sufficient bug report so I can fix the problem.

*** Bugs ***
-If Om crashes, REPORT THE BUG. Things can't get fixed if I don't know about
-them, and if you report it, it will get fixed - probably immediately.

+I write these tens of thousands of lines of code and give it to you completely

-Please, report the bug. There's a nice form on the Savannah page to do so,
-no mailing required.
