 =head1 common.mmh and platform.mmh Syntax
 
-The fshell build system uses a number of macros to control what should be built and how. These are defined in F<fshell/build/common/common.mmh> and F<fshell/platforms/E<lt>PLATFORME<gt>/platform.mmh>. Each platform defines the things it does and doesn't support in its platform.mmh. common.mmh takes these and defines some derived macros. This system allows fshell to be built in a large number of configurations, ranging from minimal base textshell on Symbian OS v9.1 to full GUI on the latest Symbian Foundation codeline.

 Any code wishing to use the fshell conditional system should C<< #include <fshell/common.mmh> >> and use the macros below and/or the ones defined in common.mmh to decide how to behave. Below follows the complete list of things that the platform.mmh can define. This isn't the complete list of all the macros that can be I<used>, for that see common.mmh directly. common.mmh can be included anywhere that the preprocessor is used - eg in source code, MMP files, RSS files or bld.infs.

 An example platform.mmh is included below. This is for an imaginary platform based on the S^4 release, that is text-only but supports most other things. Generally the older and/or more restricted the platform is, the more C<FSHELL_NO_...> macros you have to define.
