#
# Name:     mcscour
#
# Purpose:  Bourne shell script used to scour McIDAS data files
#
# Notes:    What this script does, and how it works
#
#             MCHOME - the home directory for the McIDAS-X installation
#
#             MCDATA - the directory in which the XCD decoders will
#                      create/update data and ancillary data files
#                      NOTE: data files (e.g. MD and GRID) will probably be
#                      located in other directories but can be located
#                      by REDIRECTions contained in $MCDATA/LWPATH.NAM.
#                      MCDATA is typically the working directory for
#                      the user 'mcidas'.
#
#             MCPATH - a colon separated list of directories that contain
#                      McIDAS data files, ancillary data files, and help
#                      files
#
#             PATH -   a search PATH that contains the directory of
#                      McIDAS executables.  NOTE that in this PATH
#                      the mcidas/bin directory MUST be before the
#                      directory in which this file, xcd_run, exists
#
#             LD_LIBRARY_PATH - the search path for sharable libraries;
#                      this should be the same search path as the one
#                      used by the McIDAS session
#
#             NOTE: AIX and HP-UX users need to change LD_LIBRARY_PATH
#                   everywhere in this file to what is appropriate on
#                   their systems
#
#                   AIX:  LD_LIBRARY_PATH -> LIBPATH
#                   HPUX: LD_LIBRARY_PATH -> SHLIB_PATH
#
#
# History:  19961230 - Written for Unidata McIDAS-X, -XCD 7.10
#           19970118 - Updated comments relating to LD_LIBRARY_PATH for AIX
#                        and HP-UX users
#           19970509 - Updated to run all McIDAS scouring commands from a
#                        single invocation of mcenv
#           20000414 - Updated to scour NGM GRIDs which were moved to
#                        start at GRID file number 5501
#                      Generalize LD_LIBRARY_PATH specification of Sun
#                        SCx.x libraries
#           20030611 - Added scouring for ETAMOS and GFSMOS MD files
#           20040420 - Changed default log file to ~ldm/logs/mcscour.sh
