+;;; Markup commands and markup-list commands definitions.
+;;;
+;;; Markup commands which are part of LilyPond, are defined
+;;; in the (lily) module, which is the current module in this file,
+;;; using the `define-markup-command' macro.
+;;;
+;;; Usage:
+;;;
+;;; (define-markup-command (command-name layout props args...)
+;;; args-signature
+;;; [ #:category category ]
+;;; [ #:properties property-bindings ]
+;;; documentation-string
+;;; ..body..)
+;;;
+;;; with:
+;;; command-name
+;;; the name of the markup command
+;;;
+;;; layout and props
+;;; arguments that are automatically passed to the command when it
+;;; is interpreted.
+;;; `layout' is an output def, which properties can be accessed
+;;; using `ly:output-def-lookup'.
+;;; `props' is a list of property settings which can be accessed
+;;; using `chain-assoc-get' (more on that below)
+;;;
+;;; args...
+;;; the command arguments.
+;;; There is no limitation on the order of command arguments.
+;;; However, markup functions taking a markup as their last
+;;; argument are somewhat special as you can apply them to a
+;;; markup list, and the result is a markup list where the
+;;; markup function (with the specified leading arguments) has
+;;; been applied to every element of the original markup list.
+;;;
+;;; Since replicating the leading arguments for applying a
+;;; markup function to a markup list is cheap mostly for
+;;; Scheme arguments, you avoid performance pitfalls by just
+;;; using Scheme arguments for the leading arguments of markup
+;;; functions that take a markup as their last argument.
+;;;
+;;; args-signature
+;;; the arguments signature, i.e., a list of type predicates which
+;;; are used to type check the arguments, and also to define the general
+;;; argument types (markup, markup-list, scheme) that the command is
+;;; expecting.
+;;; For instance, if a command expects a number, then a markup, the
+;;; signature would be: (number? markup?)
+;;;
+;;; category
+;;; for documentation purpose, builtin markup commands are grouped by
+;;; category. This can be any symbol. When documentation is generated,
+;;; the symbol is converted to a capitalized string, where hyphens are
+;;; replaced by spaces.
+;;;
+;;; property-bindings
+;;; this is used both for documentation generation, and to ease
+;;; programming the command itself. It is list of
+;;; (property-name default-value)
+;;; or (property-name)
+;;; elements. Each property is looked-up in the `props' argument, and
+;;; the symbol naming the property is bound to its value.
+;;; When the property is not found in `props', then the symbol is bound
+;;; to the given default value. When no default value is given, #f is
+;;; used instead.
+;;; Thus, using the following property bindings:
+;;; ((thickness 0.1)
+;;; (font-size 0))
+;;; is equivalent to writing:
+;;; (let ((thickness (chain-assoc-get 'thickness props 0.1))
+;;; (font-size (chain-assoc-get 'font-size props 0)))
+;;; ..body..)
+;;; When a command `B' internally calls an other command `A', it may
+;;; desirable to see in `B' documentation all the properties and
+;;; default values used by `A'. In that case, add `A-markup' to the
+;;; property-bindings of B. (This is used when generating
+;;; documentation, but won't create bindings.)
+;;;
+;;; documentation-string
+;;; the command documentation string (used to generate manuals)
+;;;
+;;; body
+;;; the command body. The function is supposed to return a stencil.
+;;;
+;;; Each markup command definition shall have a documentation string
+;;; with description, syntax and example.
