#W gapd.sh The SCSCP package Alexander Konovalov
#W Steve Linton
##
## gapscscp.sh [-h host] [-a] [-l] [-u] [-p port] [-t]
##
## The following options may be used to overwrite the default method to
## specify the hostname to run GAP SCSCP server, stated in scscp/config.g :
##
## 1) if '-h host' is specified, then the server will be started at 'host'.
## 'host' may be given as machine name with or without domain or even as
## 'localhost', though we have -l option for that purpose
##
## 2) if '-a' is specified, then the output of the call to 'hostname' will
## be used as the SCSCP server address
##
## 3) if '-l' is specified, then the server will be started at localhost
## and will not accept any incoming connections from the outside
##
## 4) if '-u' is specified, the server will be started in a "universal"
## mode and will accept all incoming connections
##
## The options 1-4 above are incompatible, so in case several of them will
## be given, only the option with the biggest number will be used
##
## If none of the options 1-4 above is stated, the hostname for the server
## will be taken from the scscp/config.g file
##
## Additionally, you may use the following options:
##
## 5) if '-p port' is specified, this will overwrite the default port for
## the SCSCP server given in scscp/config.g
##
## 6) if '-t' is specified than the output will be redirected to a
## temporary file, which name will be displayed on screen during
## startup. Otherwise, by default it will be redirected to /dev/null
##

## PART 1. MODIFY PATHS IF NEEDED
##
###########################################################################
##
## Define the local call of GAP and call options, if necessary, for
## example, memory usage, start with the workspace etc. The path may be
## relative (to start from this directory) or absolute.
##
GAP="../../bin/gap.sh -b -r"
##
###########################################################################
##
## Define the configuration file for the SCSCP server. Note that since GAP
## reads the configuration file immediately before starting SCSCP server,
## you may redefine in it all variables that were set to their default
## values in scscp/config.g and scscp/configpar.g files (explicitly or
## reading your appropriately modified private copies of that files).
## The path may be relative (to start from this directory) or absolute.
##
SCSCP_CONFIG="example/myserver.g"
