/****************************************************************
this program runs its arguments as a command. it essentially
does what the sh would do to look for the command. if / occurs in
the command it runs it as is, otherwise it search the PATH
variable. care is taken to preserve the PATH variable that is
passed (as part of the environment) to the command being invoked.
the signals SIGINT and SIGQUIT are set to the default action
before running the command.
This program is needed because the GIS shell must ignore
interrupts when it runs the user's shell. There is no way to tell
the user's shell to re-activate interrupts in shell-ese.
