# The invoking script must set the shell variable `Usage' to a string

Help="\
$Usage
Options:
	-h, --help
		Print this help message.

Diagnostics options:
	-v, --verbose
		Print each command before executing it.
	--no-demangle
		Don't pipe the output of the linker through the Mercury
		demangler.
	--allow-undef
	--allow-undefined
		Don't report an error if there are unresolved symbols.
		This option is only used if you are building a shared
		library (with \`--make-shared-lib); when building
		executables, unresolved symbols are always errors.
		This option is useful when building shared libraries
		that are not intended to be self-contained.
	--print-grade
		Compute the grade of the Mercury libraries to link with based
		on the command line options, print it to the standard output,
		and then exit (don't actually link anything).
	--print-gc-grade
		Compute the base name of the garbage collection library to
		link with based on the command line options, print it to the
		standard output, and then exit (don't actually link anything).
	--print-link-command
		Print the command used to link executables.
	--print-shared-lib-link-command
		Print the command used to link shared libraries.
	--print-map
		Print a link map, via \`ld --print-map'.

Dynamic/static linking options:
	--mercury-libs {shared, static, none}
		Specify which version of the standard Mercury libraries to
		link with:
			--mercury-libs shared
				Link with the shared libraries (*.so),
				if possible, otherwise with the static ones.
			--mercury-libs static
				Link with the static libraries (*.a).
			--mercury-libs none
				Don't link in the Mercury standard libraries.
	-shared, --shared
		Similar to \`--mercury-libs shared', but applies to all
		libraries, not just the standard Mercury libraries.
	-static, --static
		Similar to \`--mercury-libs static', but applies to all
		libraries, not just the standard Mercury libraries.
	--make-shared-lib
		Produce a shared library, rather than an executable.

Directory options:
	--mercury-standard-library-directory <directory>
	--mercury-stdlib-dir <directory>
		The directory in which to find the Mercury standard library.
	--no-mercury-standard-library-directory, --no-mercury-stdlib-dir
		Same as \`--mercury-libs none'.
	--mercury-config-directory <directory>
	--mercury-config-dir <directory>
		The location of an alternative configuration
		(created with mercury_config) to use.
	-L <directory>, --lib-dir <directory>
		Include <directory> in the list of directories that the
		linker will use to search for libraries.
	-R <directory>, --shared-lib-dir <directory>
		Include <directory> in the list of directories that the
		dynamic linker will use to search for shared libraries.
	--leave-shared-lib-dirs-relative
		Don't convert relative shared library directory names
		into absolute paths.
	--no-leave-shared-lib-dirs-relative
		Convert relative shared library directory names into
		absolute paths.  This is the default.

Debugging options:
	-t, --trace
		Link in the Mercury debugging libraries.
		This option is needed if any of the modules being linked
		were compiled with tracing enabled.  However, \`--debug'
		implies \`--trace', so if you're using \`--debug',
		then you don't need to explicitly specify \`--trace'.
		Note that \`--trace' is incompatible with \`--static'
		on some platforms (e.g. sparc-sun-solaris2.6).
		Implies \`--include-initialization-code'.
	-r-, --no-readline
		Don't link in the GPL'd GNU Readline Library.
	-g, --c-debug, --no-strip
		Do not strip C debugging information.

Initialization options:
	--no-main, --library
		Don't generate a \`main()' function.
		Instead, generate a function
			mercury_main(int argc, char **argv);
		(declared in \"mercury_init.h\") that can be called
		from C code.
		(A more fine-grained interface is also available;
		see \"mercury_init.h\" for details.)
	-I <directory>, --init-file-directory <directory>
		Include <directory> in the list of directories searched to
		locate \`.init' files.
	-w <label>, --entry-point <label>
		Set entry point to <label>.
		(Default value corresponds to main/2.)
	--runtime-flags <flags>
		Add <flags> to the list of flags to pass to the
		Mercury runtime.  Flags can also be passed at runtime
		in the MERCURY_OPTIONS environment variable.
		For the list of available flags, see the documentation
		for MERCURY_OPTIONS in the "Environment" chapter
		of the Mercury User's Guide.
	--experimental-complexity <filename>
		Set up for the experimental determination of the complexity
		of the procedures listed in the given file.
	--init-c-file <filename>
		Output the generated C initialization program to the
		specified file, rather than sending it to the standard
		output.
	-A <funcname>
		Always execute the named void function (which must take no
		arguments) when the Mercury runtime is initialized.
	-x, --extra-inits
		Search \`.c' files for extra initialization functions.
		(This may be necessary if the C files contain
		hand-coded C code with \`INIT' comments, rather than
		containing only C code that was automatically generated
		by the Mercury compiler.)

Threads options:
	--use-thread-libs
		Link with the POSIX thread libraries. This option is useful
		if a C library being linked with uses threads, but the
		Mercury code being linked doesn't.

# The following options are not generally useful, so they are not documented:
# -i, --include-initialization-code
# 	Always include code that calls the initialization functions
# 	of the various modules. With this option, the debugger can use
# 	information from any modules that were compiled with execution
# 	tracing to print (partial) stack traces, and to print the
# 	values of variables in ancestors of the current call, even
# 	in grades in which this not normally possible.
#	(It's usually better just to use `--trace').
# -c <n>, --max-calls <n>
#         Break up the initialization into groups of at most <n> function
#         calls.  (Default value of <n> is 40.)

# canonical_grade.sh-subr:
#	An `sh' subroutine for computing a canonical grade string based on
#	the values of grade-related options.
#	It is used by the `ml', `c2init' and `canonical_grade' scripts.
#
#	The code here should be inserted after init_grade_options.sh-subr,
#	parse_grade_options.sh-subr and final_grade_options.sh-subr, which
#	together define a set of shell variables giving the values of the
#	various grade options.
#
#	Canonical_grade.sh-subr defines the variable GRADE, which will contain
#	the canonical string for the grade implied by the option values.
#
#	If the option values are inconsistent, this script fragment will
#	print an error message and exit with failure.
#
# IMPORTANT: any changes to the handling of grades here may also require
# changes to all the files indicated by runtime/mercury_grade.h.
