# pashua_run
#
# original script by Carsten Blum, developer of Pashua
#
# Modified by Wataru Kagawa (06/02/05)
# wkagawa@jota.gsc.riken.go.jp
#
# with help from Bill Scott (wgscottATchemistryDOTucscDOTedu).
#
# The original bash script that executes Pashua was modified to a zsh function that can
# be autoloaded.
#
# USAGE:
# pashua_run "<configuration>"
#
# For example,
#
# pashua_run "windowtitle = Hello World! \n tx_type = text \n tx_text = This is a test."
#
# For details on the configuration syntax, see inside the Documentation folder that
# comes with the Pashua program.  Pashua is available at,
#
# http://www.bluem.net/downloads/pashua_en/
