Define entry points within an SFK script, or define locations to jump to with sfk label.

sfk label name [options] +...
sfk ... +label name +...

define a label at the beginning or within an sfk script.
a label is a user-defined name that can be jumped to
by the sfk script command.

global options

   All options after "label" are global and therefore
   valid for all following commands.

   -prefix=s    set user-defined input parameter name prefix.

   by default, parameters passed into sfk scripts are called $1 to $9,
   or %1 to %9. with -prefix, you can define your own parameter names,
   e.g. if you rewrite the sfk label line like this:

      sfk label begin -prefix=$parm

   then the input parameters are renamed to $parm1, $parm2, ...
   accepting no other names. or simply say

      sfk label begin -prefix=%

   to accept ONLY %1 to %9 but NOT $1 to $9, to get around conflicts
   with script commands using expressions like "$10.10col1".

   -var         enable use of variables like #(name)

   -qtrim       automatic reformatting of quoted multi line
                parameters depending on target command.
                this is default since SFK 1.8.0.
                e.g. +echo will keep line ends and some leading
                spaces to apply auto indentation, while +xed
                will strip all leading spaces and line ends.
                see "sfk script" for details.

   -qraw        do not reformat quoted multi line parameters.
                this was default with sfk up to 1.7.7.
                since sfk 1.8.0 some old scripts may need:
                   sfk label labelname -qraw
                or via environment variable:
                   set SFK_CONFIG=qraw

   options must be given after the label name.
   if -prefix is used it must be the first option.

   sfk samp sfkbat mytest.bat
      creates a windows batch file mytest.bat
      with an embedded sfk command script.

   sfk samp sfkbash mytest
      creates a linux batch file mytest
      with an embedded sfk command script.
