-I knew it would... And leaving out some of them is perfectly fine
-with me.
-I do think that a list like this, with the main contexts and a
-brief
-description of what they do (perhaps also with a note about what
-default
-behavior is associated with each of them, but this may be
-unmanageable),
-should be there, and then we could simply list the remaining ones
-without
-further explanation and with links to the IR.
-
-
-The Master Of All Contexts
-==========================
-
- * Score
- This is the top level notation context. No other context
-can
- contain a Score context. This context handles the
- administration of time signatures. It also makes sure that
- items such as clefs, time signatures, and key-signatures
-are
- aligned across staves.
- You cannot explicitly instantiate a Score context (since
-it is
- not contained in any other context). It is instantiated
- automatically when an output definition (a \score or
-\layout
- block) is processed.
- (it should also be made clear somewhere what the
-difference is between
- \score and \Score).
-
-Top-level contexts: Staff containers
-====================================
- * StaffGroup
- Groups staves while adding a bracket on the left side,
- grouping the staves together. The bar lines of the
-contained
- staves are connected vertically. StaffGroup only consists
-of a
- collection of staves, with a bracket in front and spanning
-bar
- lines.
- * ChoirStaff
- Identical to StaffGroup except that the contained staves
-are
- not connected vertically.
- * GrandStaff
- A group of staves, with a brace on the left side, grouping
-the
- staves together. The bar lines of the contained staves are
- connected vertically.
- * PianoStaff
- Just like GrandStaff but with a forced distance between
-the
- staves, so cross staff beaming and slurring can be used.
- * DrumStaff
- Handles typesetting for percussion. Can contain DrumVoice
- * InnerStaffGroup
- * InnerChoirStaff
-
-Staff-level contexts
-====================
- * Staff
- Handles clefs, bar lines, keys, accidentals. It can
-contain
- Voice contexts.
- * RhythmicStaff
- Like Staff but for printing rhythms. Pitches are
- ignored; the notes are printed on one line.
- * TabStaff
- Context for generating tablature. By default lays the
-music
- expression out as a guitar tablature, printed on six
-lines.
- * VaticanaStaff
- Same as Staff, except that it is accommodated for
- typesetting a piece in gregorian style.
- * MensuralStaff
- Same as Staff, except that it is accommodated for
- typesetting a piece in mensural style.
-
-Voice-level (bottom) contexts
-=============================
-What is generated by default here? The voice-level contexts
-initiate
-certain properties and start engravers.
-
- * Voice
- Corresponds to a voice on a staff. This context handles
-the
- conversion of dynamic signs, stems, beams, super- and
- subscripts, slurs, ties, and rests.
- You have to instantiate this explicitly if you want to
-have
- multiple voices on the same staff.
- Bottom context.
- * VaticanaVoice
- Same as Voice, except that it is accommodated for
- typesetting a piece in gregorian style.
- * MensuralVoice
- Same as Voice, except that it is accommodated for
- typesetting a piece in mensural style.
- * Lyrics
- Corresponds to a voice with lyrics. Handles the printing
-of a
- single line of lyrics.
- Bottom context.
- * DrumVoice
- A voice on a percussion staff.
- * FiguredBass
-
- * ChordNames
- Typesets chord names. This context is a `bottom' context;
-it
- cannot contain other contexts.
-
-------------------------------
-Then the following, which I don't know what to do with:
-
- * TabVoice
- * GregorianTranscriptionVoice
- * GregorianTranscriptionStaff
-
- * FretBoards
- Engraves fretboards from chords. Not easy... Not
-documented.
- * NoteNames
-
- * CueVoice Not documented
- * Global
- Hard coded entry point for LilyPond. Cannot be tuned.
- * Devnull
- Silently discards all musical information given to this
-context.

-@node another thing FIXME
-@subsection another thing FIXME

-Another thing that is needed, is an overview of the various naming
-conventions:
-
- scheme functions: lowercase-with-hyphens (incl. one-word
-names)
- scheme functions: ly:plus-scheme-style
- music events, music classes and music properties:
-as-scheme-functions
- Grob interfaces: scheme-style
- backend properties: scheme-style (but X and Y!)
- contexts (and MusicExpressions and grobs): Capitalized or
-CamelCase
- context properties: lowercaseFollowedByCamelCase
- engravers:
-Capitalized_followed_by_lowercase_and_with_underscores
-
-Which of these are conventions and which are rules?
-Which are rules of the underlying language, and which are
-LP-specific?
