DOC is a general description and shows up in all docstrings.

It is followed by a list of keywords and functions:
|

|
|
:expand FUNC Expansion function. This function should accept
|
|
two positions in the current buffer, BEG and END,
|
|
and return a pair of expanded buffer positions.
|
|
:contract FUNC The opposite of :expand, optional.
|
|
:one-to-one BOOL Whether expansion is one-to-one. This means that
|
|
:expand followed by :contract always returns the
|
|
original range.
|
|
:normalize FUNC Normalization function, optional. This function should
|
|
accept two unexpanded positions and adjust them before
|
|
expansion. May be used to deal with buffer boundaries.
|
|
:string FUNC Description function. This takes two buffer positions
|
|
and returns a human-readable string, for example,
|
|
\"2 lines\".
|
|
|
|
If further keywords and functions are specified, they are assumed to

be transformations on buffer positions, like :expand and :contract.
