[Mono-dev] Cross compiling options explained

[Barry Bennett]

Can anyone provide more details on what the cross compiling options 
for building really mean?

The --help option for configure provides the following terse 
responses relating to cross compiler options:
   --build=BUILD     configure for building on BUILD [guessed]
   --host=HOST       cross-compile to build programs to run on HOST [BUILD]
   --target=TARGET   configure for building compilers for TARGET [HOST]

What are the allowable settings for BUILD, HOST, and TARGET?

What do the bracketed words at the ends of each line mean?

Are there any examples of using these options that might help to 
clarify their meaning?

I have searched for documentation on these options without 
success.  If they are documented somewhere then can someone please 
point me to the link.

Thanks!
