NAME
       bsescm - A Guile based scheme shell for Beast and Bse.

SYNOPSIS
       bsescm [options] [--] ...

       bsescm [options] <infile.bse> ...

DESCRIPTION
       bsescm is a Guile based scheme shell for Bse, the Better Sound Engine.

       bsescm provides a shell interface to all procedures exported by the Bse
       library, so scripts are able to access the full range of functionality
       provided by it, from simple playback of a .bse file to full fledged
       automated creation or editing of synthesis networks.

       Alternatively to the linked in Bse library, the bsescm language
       interface can also talk to a remotely running Bse library host, for
       instance Beast.  By operating on a remotely running Bse core, bsescm
       can be used to script arbitrary Bse programs. The shell is also used
       directly by the Bse library to execute procedures on its behalf, this
       allows Bse procedures to be written in scheme.

       When started, bsescm tests whether the first non-option argument is a
       .bse file and if the test succeeds, attempts to play the command line
       arguments as .bse files.

OPTIONS
       bsescm follows the usual GNU command line syntax, with long options
       starting with two dashes ('--').

       --bse-pipe infd outfd
              Provide the input and output communication filedescriptors for
              remote operation.

       --bse-eval string
              Execute (eval-string string) instead of going into interactive
              mode.

       --bse-enable-register
              Allowes registration of procedures with the Bse core.

       --bse-no-load
              Prevent automated loading of plugins and scripts at startup time
              in interactive mode.

       --bse-no-play
              Prevent automated detection and playback of .bse file command
              line arguments.

       --g-fatal-warnings
              Make runtime warnings fatal (abort).

       -h, --help
              Describe command line options and exit.

       -v, --version
              Display version and exit.

       -n=nicelevel
              Execute with priority nicelevel, this option only takes effect
              for the root suid wrapper 'beast'.

       -N     Disables renicing to execute with existing priority.

       --bse-latency=useconds
              Set the allowed synthesis latency for Bse in milliseconds.

       --bse-mixing-freq=frequency
              Set the desired synthesis mixing frequency in Hz.

       --bse-control-freq=frequency
              Set the desired control frequency in Hz, this should be much
              smaller than the synthesis mixing frequency to reduce CPU load.
              The default value of approximately 1000 Hz is usually a good
              choice.

       --bse-pcm-driver driver-conf

       -p driver-conf
              This options results in an attempt to open the PCM driver
              driver-conf when playback is started. Multiple options may be
              supplied to try a variety of drivers and unless driver-conf is
              specified as "auto", only the drivers listed by options are
              used. Each driver-conf consists of a driver name and an optional
              comma seperated list of arguments attached to the driver withan
              equal sign, e.g.: -p oss=/dev/dsp2,rw -p auto

       --bse-midi-driver driver-conf

       -m driver-conf
              This option is similar to the --bse-pcm-driver option, but
              applies to MIDI drivers and devices. It also may be specified
              multiple times and features an "auto" driver.

       --bse-driver-list
              Produce a list of all available PCM and MIDI drivers and
              available devices.

   Guile Options:
       -l file
              Load scheme source code from file.

       -e function
              After reading script, apply function to command-line arguments.

       -ds    Do -s script at this point (note that this argument must be used
              in conjuction with -s).

       --debug
              Start with debugging evaluator and backtraces enabled (useful
              for debugging scripts).

       --emacs
              Enable emacs protocol for use from within emacs (experimental).

       The remaining Guile options stop argument processing, and pass all
       remaining arguments as the value of (command-line):

       --     Stop argument processing, start in interactive mode.

       -c expr
              Stop argument processing, evaluate expr as a scheme expression.

       -s script
              Load Scheme source from script and execute as a script.
