Learning NAnt - what does [+|-] in the help mean?

Question

If I type nant -help I receive help information about the various command-line options.

Some, such as find have a suffix of [+|-], e.g.

-find[+|-]                     Search parent directories for build file

What does the [+|-] mean?

Answer 1

In command line options syntax, sometimes [...] is used to denote optional items, and | is used to denote alternate. So it looks like there are 3 different variations here:

-find
-find+
-find-

The documentation should clarify what each of these variation means.
