;;;
;;; args...
-;;; the command arguments. There are restrictions on the
-;;; possible arguments for a markup command.
-;;; First, arguments are distingued according to their type:
-;;; 1) a markup (or a string), corresponding to type predicate `markup?'
-;;; 2) a list of markups, corresponding to type predicate `markup-list?'
-;;; 3) any scheme object, corresponding to type predicates such as
-;;; `list?', 'number?', 'boolean?', etc.
-;;; The supported arrangements of arguments, according to their type, are:
-;;; - no argument
-;;; - markup
-;;; - scheme
-;;; - markup, markup
-;;; - markup-list
-;;; - scheme, scheme
-;;; - scheme, markup
-;;; - scheme, scheme, markup
-;;; - scheme, scheme, markup, markup
-;;; - scheme, markup, markup
-;;; - scheme, scheme, scheme
-;;; This combinations are hard-coded in the lexer and in the parser
-;;; (lily/lexer.ll and lily/parser.yy)
+;;; 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
+;;; 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.
;;;
;;; category
;;; for documentation purpose, builtin markup commands are grouped by
-;;; category. This can be any symbol. When documentation is generated,
+;;; 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
+;;; 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
+;;; 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
+;;; to the given default value. When no default value is given, #f is
;;; used instead.
;;; Thus, using the following property bindings:
;;; ((thickness 0.1)
;;; ..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
+;;; 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

+Draws a path with line thickness @var{thickness} according to the

+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.

+current subpath in the active path.
