The short function description cannot be multiline, but the other
descriptions can be (and they can contain blank lines). Avoid putting a
spurious blank line after the function name, or else the description will
be repeated!
The short function description ***cannot be multiline***, but the other
descriptions can be (and they can contain blank lines). If you continue
that initial short description onto a second line, that second line will
appear further down at the beginning of the description section, which is
almost certainly not what you had in mind.

All descriptive text is further processed, scanning for the following special

'@parameter' - name of a parameter
'%CONST' - name of a constant.
NOTE 1: The multi-line descriptive text you provide does *not* recognize
line breaks, so if you try to format some text nicely, as in:
Return codes
0 - cool
1 - invalid arg
2 - out of memory
this will all run together and produce:
Return codes 0 - cool 1 - invalid arg 2 - out of memory
NOTE 2: If the descriptive text you provide has lines that begin with
some phrase followed by a colon, each of those phrases will be taken as
a new section heading, which means you should similarly try to avoid text
like:
Return codes:
0: cool
1: invalid arg
2: out of memory
every line of which would start a new section. Again, probably not
what you were after.
Take a look around the source tree for examples.
