NAME

       seed - libseed JavaScript REPL/Interpreter.

SYNOPSIS

       seed [OPTION...] [SCRIPT]

DESCRIPTION

       seed acts as a simple read-eval-print loop for libseed's GObject JavaScriptCore bindings, unless the path to a script to interpret is spec-
       ified.

OPTIONS

       --help Show these help options.

       --version
	      Print interpreter version.

       -e expression
	      Takes the JavaScript expression, checks its syntax, and evaluates it, printing the return value.

       --seed-debug=DEBUGFLAGS
	      Show debug messages, filtered by the specified debug flags. If one wishes to see all possible debug messages, specify the flag "all"
	      (keep  in mind that this will produce a significant amount of output). Otherwise, specify a comma-separated list of: misc, finaliza-
	      tion, initialization, signal, invocation, structs, construction, gtype, importer, module.

srand - Seed the random number generator

SYNOPSIS

       void srand ([int  $seed])

DESCRIPTION

	Seeds the random number generator with $seed or with a random value if no $seed is given.

       Note

	      As  of  PHP  4.2.0,  there is no need to seed the random number generator with srand(3) or mt_srand(3) as this is now done automati-
	      cally.

PARAMETERS

	      o $seed
		- Optional seed value

RETURN VALUES

	No value is returned.
