* The following defines control the inclusion of "optional" features. As
* the code size of the editor grows, it will probably be useful to be able
* to tailor the editor to get the features you most want in environments
* with code size limits.
*
* TILDEOP
* Normally the '~' command works on a single character. This define
* turns on code that allows it to work like an operator. This is
* then enabled at runtime with the "tildeop" parameter.
*
* HELP
* If defined, a series of help screens may be views with the ":help"
* command. This eats a fair amount of data space.
*
* TERMCAP
* Where termcap support is provided, it is generally optional. If
* not enabled, you generally get hard-coded escape sequences for
* some "reasonable" terminal. In Minix, this means the console. For
* UNIX, this means an ANSI standard terminal. See the file "term.h"
* for details about specific environments.
