+%D \macros
+%D {JS*}
+%D
+%D Because \JAVASCRIPT's are activated by the user, for
+%D instance by activating on a button, their support is closely
+%D related to the referencing mechanism. Integration takes
+%D place by
+%D
+%D \starttyping
+%D \goto{calculate total}[Sum()]
+%D \stoptyping
+%D
+%D The \type{()} classify this as a script. If they are absent,
+%D the keyword is treated as a normal reference.
+%D
+%D One can pass arguments to such a script by saying:
+%D
+%D \starttyping
+%D \goto{calculate total}[Sum(1.5,2.3)]
+%D \stoptyping
+
+
+%D \macros
+%D {startJScode}
+%D
+%D A piece of \JAVASCRIPT\ code is defined by saying:
+%D
+%D \starttyping
+%D \startJScode{name}
+%D name = 4 ;
+%D \stopJScode
+%D \stoptyping
+%D
+%D This assumes uses no preamble or presumes that the preamble is
+%D always loaded, the next definition also tells \CONTEXT\ to
+%D actually include the preamble needed.
+%D
+%D \starttyping
+%D \startJScode{uses} uses {later}
+%D uses = 6 ;
+%D \stopJScode
+%D \stoptyping
+%D
+%D \macros
+%D {startJSpreamble}
+%D
+%D One can define insert \JAVASCRIPT\ code at the document level
+%D by using:
+%D
+%D \starttyping
+%D \startJSpreamble{oeps}
+%D oeps = 1 ;
+%D \stopJSpreamble
+%D \stoptyping
+%D
+%D which is the same as:
+%D
+%D \starttyping
+%D \startJSpreamble{now} used now
+%D now = 2 ;
+%D \stopJSpreamble
+%D \stoptyping
+%D
+%D while the next definition is only included when actually
+%D used.
+%D
+%D \starttyping
+%D \startJSpreamble{later} used later
+%D later = 3 ;
+%D \stopJSpreamble
+%D \stoptyping
+%D
+%D This command may be used more that once, but always before
+%D the first page is shipped out.
+%D
+%D \macros
+%D {setJSpreamble, addtoJSpreamble}
+%D
+%D In addition to the previous preamble definitions, we can
+%D set a preamble \quote {in||line} and add tokens to a
+%D preamble.
+%D
+%D \macros
+%D {useJSpreamblenow}
+%D
+%D This macro can be used to force inclusion of postponed
+%D \JAVASCRIPT\ preambles.

+%D \macros
+%D {useJSscripts}
+%D
+%D In due time, users will build their collections of scripts,
+%D which can be used (loaded) when applicable. Although not all
+%D public, we will provide some general purpose scripts,
+%D collected in files with names like \type{java-...}. One can
+%D load these scripts with \type{\useJSscripts}, like:
+%D
+%D \starttyping
+%D \useJSscripts[fld]
+%D \stoptyping
+%D
+%D The not so complicated implementation of this macro is:
