+;;; 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.

+@cindex drawing paths
+Draws a path with line thickness @var{thickness} according to the
+directions given in @var{commands}.  @var{commands} is a list of
+lists where the @code{car} of each sublist is a drawing command and
+the @code{cdr} comprises the associated arguments for each command.
+
+Line-cap styles and line-join styles may be customized by
+overriding the @code{line-cap-style} and @code{line-join-style}
+properties, respectively.  Available line-cap styles are
+@code{'butt}, @code{'round}, and @code{'square}.  Available
+line-join styles are @code{'miter}, @code{'round}, and
+@code{'bevel}.
+
+The property @code{filled} specifies whether or not the path is
+filled with color.
+
+There are seven commands available to use in the list
+@code{commands}: @code{moveto}, @code{rmoveto}, @code{lineto},
+@code{rlineto}, @code{curveto}, @code{rcurveto}, and
+@code{closepath}.  Note that the commands that begin with @emph{r}
+are the relative variants of the other three commands.
+
+The commands @code{moveto}, @code{rmoveto}, @code{lineto}, and
+@code{rlineto} take 2 arguments; they are the X and Y coordinates
+for the destination point.
+
+The commands @code{curveto} and @code{rcurveto} create cubic
+Bézier curves, and take 6 arguments; the first two are the X and Y
+coordinates for the first control point, the second two are the X
+and Y coordinates for the second control point, and the last two
+are the X and Y coordinates for the destination point.
+
+The @code{closepath} command takes zero arguments and closes the
+current subpath in the active path.
+
+Note that a sequence of commands @emph{must} begin with a
+@code{moveto} or @code{rmoveto} to work with the SVG output.
