+ .SH DESCRIPTION
+ The Mozilla JavaScript Shell
+ .B js
+ is a command line interface to the
+ .B Mozilla JavaScript
+ language engine ("SpiderMonkey"),
+ as provided by the
+ .B OSSP js
+ distribution.
+ The
+ .B js
+ program provides a test vehicle for easily evaluating JavaScript scripts, calling JavaScript functions,
+ trying out debugger primitives, etc.
+ .SH OPTIONS
+ .SS Compile-Time Options
+ .TP 8
+ .B -w
+ Disable the printing of warnings.
+ .TP 8
+ .B -W
+ Enable the printing of warnings.
+ .TP 8
+ .B -s
+ Enable strict language parsing during compile-time.
+ This will print warnings on dubious JavaScript programming practices.
+ .TP 8
+ .B -x
+ Enable ECMAScript for XML (E4X) support during compile-time.
+ .TP 8
+ .B -C
+ Compile only. This compiles the script but does not
+ execute it.
+ .SS Run-Time Options
+ .TP 8
+ .BI -c " stackchunksize"
+ Set the stack chunk size to
+ .I stackchunksize
+ bytes. The default is
+ .BR 8192 .
+ .TP 8
+ .BI -S " maxstacksize"
+ Set a maximum stack size limit to
+ .I maxstacksize
+ bytes in order to restruct script resource consumption.
+ The default is a stack of unlimited size.
+ .TP 8
+ .BI -b " maxbranches"
+ Set a maximum branch number limit to
+ .I maxbranches
+ in order to restrict script resource consumption. The default is an
+ unlimited number of branches.
+ .TP 8
+ .B -P
+ Sets the global object????
+ .TP 8
+ .BI -v " version"
+ override the numerical JavaScript version number, which the JavaScript
+ .B version()
+ function returns, with the value
+ .IR version .
+ The argument
+ .I version
+ usually is one of the following integer values:
+ .B 0
+ (default),
+ .B 100
+ (JS 1.0),
+ .B 110
+ (JS 1.1),
+ .B 120
+ (JS 1.2),
+ .B 130
+ (JS 1.3),
+ .B 140
+ (JS 1.4),
+ .B 148

+ (JS 1.5),
+ .B 160
+ (JS 1.6).
+ .SS Script Execution
+ .TP 8
+ .BI -e " script"
+ Command-line passed JavaScript script to execute.
+ This is executed immediately during command
+ line parsing, so specify it after
+ .B "Compile-Time Options"
+ and
+ .BR "Run-Time Options" .
+ .TP 7
+ .BI -f " scriptfile"
+ Externally passed JavaScript script to execute.
+ This is executed immediately during command
+ line parsing, so specify it after
+ .B "Compile-Time Options"
+ and
+ .BR "Run-Time Options" .
+ .SH ARGUMENTS
+ .TP 8
+ .RI scriptfile
+ Externally passed JavaScript script to execute.
+ This is executed after command line parsing
+ (and this way after scripts of options
+ .BR -e " and " -f
+ were executed.
+ This additional way of executing an external JavaScript
+ script exists to especially support Unix "shebang"
+ style scripts.
+ .TP 8
+ .IR scriptarg
+ Zero or more arguments which are passed to the executed
+ .IR scriptfile .
+ They are available in the script through the global
+ array object
+ .BR arguments .
