# spewcmd: launch one of those GUI programs that spew trash to the terminal
#
# This script automates the process of quieting those evil spewhappy
# GTK/Qt/FreeDesktop/whatervergarbage programs, so one can be launched
# from the terminal without rendering it useless for all other tasks.
# Typical usage is something like:
#
# spewcmd <command> <options...>
#
# where <options...> will be passed as <command>'s arguments. If
# spewcmd itself ever grows options, they will only occur *before*
# <command> is specified.
#
# This will cause stdout and stderr from <command> to go to
# /tmp/<command>.spew; <command> will be backgrounded automatically.
# If /tmp/<command>.spew already exists, the form /tmp/<command>.n.spew
# is used, where n begins as '1' and is incremented until we get a file
# that doesn't exist yet. If <command> is an absolute or relative path, only the
# last component will be used in the temporary file's name.
# envvar PREFIX
#
# Prefix for the spewfile's path; defaults to /tmp. Override with env(1) or
# similar if desired, your value will have a / appended.
