+#  Name:
+#     makefile
+#
+#  Version:
+#     Library makefile Mk V
+#
+#  Purpose:
+#     Build and install the SLALIB package.
+#
+#  Type of Module:
+#     Description file for the make utility.
+#
+#  Description:
+#     This description file is used by the make utility to build the
+#     SLALIB package from the distributed source files, to install
+#     the resulting system for use, and to perform other housekeeping
+#     tasks.
+#
+#  Invocation:
+#     This makefile is not intended to be used by make when invoked
+#     directly (although this is possible), but instead to be used via
+#     the accompanying mk script.  This script sets up a number of
+#     environment variables which are used as macros within the
+#     makefile and which accommodate differences between machines and
+#     operating systems (it invokes make with the -e option).  Please
+#     consult the mk script prologue for full details.
+#
+#  Targets:
+#     The following make targets are defined in this script for
+#     external use:
+#
+#        [help]
+#           This is the default target.  It outputs a message describing
+#           the mk script and lists the targets provided.
+#
+#        check
+#           Performs a simple check that all necessary source files are
+#           present, and displays the version number and current state
+#           of the package (built/installed/tested, etc.).
+#
+#        build
+#           Compiles the source files and creates all files needed
+#           prior to installing the package for use.
+#
+#        install
+#           Installs the package for use by putting the necessary files
+#           into sub-directories of the $INSTALL directory (the $HOME
+#           directory is used if the environment variable INSTALL is
+#           not defined).  Links to the installed files are left in the
+#           source directory.
+#
+#        deinstall
+#           Reverses the action of the install target, removing files
+#           from sub-directories of the $INSTALL directory and
+#           restoring them to the source directory (the $HOME directory
+#           is used by default if the environment variable INSTALL is
+#           not defined).
+#
+#        test
+#           Builds and runs a simple test program to check for correct
+#           installation of the package.
+#
+#        export
+#           Produces an export copy of the built package suitable for
+#           passing to another user.  A compressed tar file is created
+#           in the $EXPORT directory containing copies of the source
+#           files and built files for the package (the current
+#           directory is used by default if the environment variable
+#           EXPORT is not defined).  The package should normally be
+#           built, installed and tested (see above) before using this
+#           target.  After unpacking the exported file on a similar
+#           machine, the recipient may simply install it for use.
+#
+#        export_run
+#           Produces an export copy of the built package suitable for
+#           passing to another user.  A compressed tar file is created
+#           in the $EXPORT directory containing copies of the built
+#           files for the package (the current directory is used by
+#           default if the environment variable EXPORT is not defined).
+#           The package should normally be built, installed and tested
+#           (see above) before using this target.  After unpacking the
+#           exported file on a similar machine, the recipient may simply
+#           install it for use.
+#
+#        export_source
+#           Produces an export copy of the source for the package
+#           suitable for passing to another user to build (possibly on
+#           a different type of machine).  A compressed tar file is
+#           created in the $EXPORT directory containing copies of just
+#           the source files for the package (the current directory is
+#           used by default if the environment variable EXPORT is not
+#           defined).  After unpacking the exported file, the recipient
+#           must build the package before installing it for use.
+#
+#        clean
+#           Cleans up after building the package, removing all
+#           intermediate files created during the building process, but
+#           leaving the built files themselves.
+#
+#        unbuild
+#           Reverses the building process, removing all intermediate
+#           files along with all the built files.
+#
+#  External Dependencies:
+#     The SLALIB package depends on the following other Starlink
+#     packages which must previously have been installed into the
+#     appropriate sub-directories of the $STARLINK directory (/star is
+#     used if the environment variable STARLINK is not defined).
+#
+#        None.
+#
+#  Notes:
+#     This makefile uses the presence/absence of the hidden files
+#     .BUILT, .INSTALLED_$(SYSTEM) and .TESTED_$(SYSTEM) to record the
+#     current state of the system during housekeeping operations.
+#
+#  Implementation Deficiencies:
+#     The method of generating the list of external libraries passed to
+#     the $(BLD_SHR) command is still preliminary.
