> perl --help
Usage: perl [switches] [--] [programfile] [arguments]
  -0[octal]       specify record separator (\0, if no argument)
  -a              autosplit mode with -n or -p (splits $_ into @F)
  -C[number/list]enables the listed Unicode features
  -c              check syntax only (runs BEGIN and CHECK blocks)
  -d[:debugger]   run program under debugger
  -D[number/list]set debugging flags (argument is a bit mask or alphabets)
  -e program      one line of program (several -e's allowed, omit programfile)
  -F/pattern/     split() pattern for -a switch (//'s are optional)
  -i[extension]   edit <> files in place (makes backup if extension supplied)
  -Idirectory     specify @INC/#include directory (several -I's allowed)
  -l[octal]       enable line ending processing, specifies line terminator
  -[mM][-]module  execute `use/no module...' before executing program
  -n              assume 'while (<>) { ... }' loop around program
  -p              assume loop like -n but print line also, like sed
  -P              run program through C preprocessor before compilation
  -s              enable rudimentary parsing for switches after programfile
  -S              look for programfile using PATH environment variable
  -t              enable tainting warnings
  -T              enable tainting checks
  -u              dump core after parsing program
  -U              allow unsafe operations
  -v              print version, subversion (includes VERY IMPORTANT perl info)
  -V[:variable]   print configuration summary (or a single Config.pm variable)
  -w              enable many useful warnings (RECOMMENDED)
  -W              enable all warnings
  -x[directory]   strip off text before #!perl line and perhaps cd to directory
  -X              disable all warnings

Code:

sleep s # Where 's' is seconds to sleep

nqp(1)							User Contributed Perl Documentation						    nqp(1)

NAME

       nqp - Not Quite Perl Compiler

SYNOPSIS

	nqp [switches] [--] [programfile] [arguments]

DESCRIPTION

       With no arguments, enters a REPL. With a "[programfile]" or the "-e" option, compiles the given program and by default also executes the
       compiled code.

	 -c		      check syntax only (runs BEGIN and CHECK blocks)
	 -e program	      one line of program
	 -h, --help	      display this help text
	 --target=[stage]     specify compilation stage to emit
	 -t, --trace=[flags]  enable trace flags, see 'parrot --help-debug'
	 --encoding=[mode]    specify string encoding mode
	 -o, --output=[name]  specify name of output file
	 -v, --version	      display version information
	 --stagestats	      display time spent in the compilation stages
	 --ll-backtrace       display a low level backtrace on errors

       Note that only boolean single-letter options may be bundled

       Supported stages for --target are:

	parse past post pir evalpmc

       where

	parse = a representation of the parse tree
	past  = an intermediate format representing the parrot abstract syntax tree
	post  = an intermediate format representing the parrot opcode syntax tree
	pir   = the parrot intermediate representation

PARROT OPTIONS

       To specify options to the underlying parrot VM, you must explicitly run parrot; you cannot specify these options by using the "perl6"
       executable.

	parrot [parrot switches] perl6.pbc [switches] [--] [programfile] [arguments]

       See "parrot --help" for a list of valid parrot options.
