.SH NAME
sweet-run \- run a script written in sweet-expressions
.SH SYNOPSIS
.ll +8
.B sweet-run
.ll -8
.br
.SH DESCRIPTION
.PP
.I sweet-run
runs an arbitrary script that is expressed using sweet-expressions.
It is typically named as the executable in the first line of a file,
somewhere after "#!".
That file's contents (after the first line)
are run through the sweet-expression filter
.I unsweeten
and the results are then executed.
.PP
Note that only the specified script is read in using
sweet-expressions; in particular, any dependencies read
in using
.I load
or
.I use-modules
are still processed as traditional s-expressions.

.SH EXAMPLES
.PP
An example use might be the following, to create a guile script using
sweet-expressions:

  #!/usr/bin/env sweet-run
  ;#!guile -s
  ;!#
  define factorial(n)
    if {n <= 1}
      1
      {n * factorial{n - 1}}

  display factorial(9)

.PP
You could replace "guile -s" with "scsh -s" to run Scheme shell (scsh)
instead of guile.
