NAME
       gosh - a Scheme script interpreter

SYNOPSIS
       gosh [-biqV] [-I path ] [-A path ] [-u module ] [-l file ] [-e expr ] [-E expr ] [-f flag ] [--] [ script argument ...  ]

DESCRIPTION
       Gosh is a stand-alone Scheme interpreter built on top of the Gauche Scheme script engine.

       When  script is given, gosh loads the script, evaluating Scheme code in it.  Then, if the script defines a procedure named main, gosh calls
       it with a single argument which is a list of the script name and subsequent arguments.  When main returns an integer value, gosh exits with
       it  as  an exit code.  If main returns non-integer value, or an error is signaled during evaluation, gosh exits with exit code 70 (EX_SOFT-
       WARE).  See SRFI-22 (http://srfi.schemers.org/srfi-22/srfi-22.html) for details.  If there's no main procedure defined in the script,  gosh
       exits with code 0 after loading the script file.

       If  no  script file is given, gosh goes into an interactive mode.  By default, gosh prompts the user to enter a Scheme expression, read and
       evaluates it, then prints the result, until EOF is read.  If the standard input is not a terminal, however, gosh doesn't print a prompt; it
       allows a user to use gosh as a filter program.  This behavior can be controlled by -i or -b option; see below.

OPTIONS
       Command line options are processed before loading the script file or entering the interactive mode.

       The  options  -I, -A, -u, -l, -L, -e and -E are processed in the order of appearance.  For example, adding a load path by -I option affects
       the -l options after it, but not the ones before it.

       -V   Prints gosh version and exits.

       -b   Batch mode.  Doesn't print prompt even the standard input is a terminal.  Supersedes -i.

       -i   Interactive mode.  Forces to print prompt, even the standard input is not a terminal.

       -q   Prevents reading the default initialization file.

       -Ipath
	    Adds path in front of the load path list.

       -Apath
	    Appends path to the tail of the load path list.

       -umodule
	    Loads and imports module, as if "(use module )" is specified in the code.

       -lfile
	    Loads a Scheme file file.

       -Lfile
	    Like -l, but doesn't complain if file doesn't exist.

       -eexpr
	    Evaluates a Scheme expression expr.

       -Eexpr
	    Same as -e, except that the expr is read as if it is surrounded by parenthesis.

       -ptype
	    Turns on the profiler.  Currently type can only be 'time'.

       -fflag
	    Sets various flags.
	      case-fold       uses case-insensitive reader (as in R5RS)
	      load-verbose    report while loading files
	      no-inline       don't inline primitive procedures and constants
			      (combined no-inline-globals, no-inline-locals, and
			      no-inline-constants.)
	      no-inline-globals don't inline global procedures.
	      no-inline-locals	don't inline local procedures.
	      no-inline-constants don't inline constants.
	      no-post-inline-pass don't run post-inline optimization pass.

       -Ffeature
	    Makes feature available in cond-expand forms.

       --   Specifies that there are no more options.  If there are more arguments after this, they are taken as script file name  and	its  argu-
	    ments.

ENVIRONMENT
       GAUCHE_LOAD_PATH
       A colon separated list of the load paths.
	      The paths are appended before the system default load paths.

       GAUCHE_DYNLOAD_PATH
       A colon separated list of the load paths for dynamically loaded
	      objects.	The paths are appended before the system default load paths.
