excerpting

Protocol

You can't change anything.

You can add, within brackets.

You can subtract. Leave elipses (...) between gaps in literal strings. To replace one or more paragraphs, use break-elipsis-break.* When eliminating text after excerpting, use "comment" markup to hide said text.

Links are, as always, fair game from existing text.

Notations can be made via footnote or sidebar.

*Break-elipsis-break:
