Org-fc: orgmode flashcards with gawk as indexer

Org-fc is a spaced-repetition system for Emacs' org-mode.

It allows you to mark headlines in a file as "flashcards", turning pieces of knowledge you want to learn into a question-answer test.

These cards are reviewed at regular interval. After each review, a Repetition Spacing Algorithm is used to calculate the next interval based on how well you remembered the contents of the card.
