#  Name:
#     lmstart   script file for starting the FLEXlm License Manager
#
#  Usage:
#     lmstart [-r matlabdir]
#	      [-c licensefile] [-d] [-l logfile] [-m marker]
#
#  Description:
#     lmstart shuts down any currently running license daemons using lmdown
#     and starts (or restarts) the license manager and vendor daemons using
#     lmboot.
#
#  Options:
#
#     -r matlabdir
#
#          Provide the MATLAB root directory path. Should be used when
#          MATLAB is in an automounted file system.
#
#     -c licensefile
#
#	    Path of the license file.
#           DEFAULT: $MATLAB/etc/license.dat
#
#     -d
#
#           The hostnames that are read from the license file should have
#           the domain name appended to them before sending to a client.
#           IMPORTANT: This means that the license file used to start up the
#                      the license manager has hostnames in the server lines
#                      WITHOUT full domain names while the license file used
#                      when running MATLAB has hostnames in the server lines
#                      WITH full domain names. You must use TWO license files.
#
#     -l logfile 
#
#	    Path of the log file.
#           DEFAULT: /usr/adm/license.log4  (except sol2)
#                    /usr/sadm/license.log4 (sol2 only)
#
#     -m marker
#
#           Marker string used to build the link names (used in lmdown
#	    and lmboot). The marker string should contain the string 'lm'
#	    so you can grep on the output of the 'ps' command using 'lm'
#	    as the search string.
#           DEFAULT: lm_TMW4
