#  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.
