------------------
-- SWITCH TABLE --
------------------
-- The switch tables contain an entry for each switch recognized by the
-- command processor. The syntax of entries is as follows:
-- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
-- TRANSLATION ::=
-- DIRECT_TRANSLATION
-- | DIRECTORIES_TRANSLATION
-- | FILE_TRANSLATION
-- | NUMERIC_TRANSLATION
-- | OPTIONS_TRANSLATION
-- | COMMANDS_TRANSLATION
-- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
-- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
-- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
-- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH #
-- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
-- COMMANDS_TRANSLATION ::= =? ARGS space command-name
-- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
-- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string
-- OPTION ::= option-name space UNIX_SWITCHES
-- ARGS ::= -cargs | -bargs | -largs
-- Here command-qual is the name of the switch recognized by the GNATCmd.
-- This is always given in upper case in the templates, although in the
-- actual commands, either upper or lower case is allowed.
-- The unix-switch-string always starts with a minus, and has no commas
-- or spaces in it. Case is significant in the unix switch string. If a
-- unix switch string is preceded by the not sign (!) it means that the
-- effect of the corresponding command qualifer is to remove any previous
-- occurrence of the given switch in the command line.
-- The DIRECTORIES_TRANSLATION format is used where a list of directories
-- is given. This possible corresponding formats recognized by GNATCmd are
-- as shown by the following example for the case of PATH
-- PATH=direc
-- PATH=(direc,direc,direc,direc)
-- When more than one directory is present for the DIRECTORIES case, then
-- multiple instances of the corresponding unix switch are generated,
-- with the file name being substituted for the occurrence of *.
-- The FILE_TRANSLATION format is similar except that only a single
-- file is allowed, not a list of files, and only one unix switch is
-- generated as a result.
-- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
-- except that the parameter is a decimal integer in the range 0 to 999.
-- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
-- more options to appear (although only in some cases does the use of
-- multiple options make logical sense). For example, taking the
-- case of ERRORS for GCC, the following are all allowed:
-- /ERRORS=BRIEF
-- /ERRORS=(FULL,VERBOSE)
-- /ERRORS=(BRIEF IMMEDIATE)
-- If no option is provided (e.g. just /ERRORS is written), then the
-- first option in the list is the default option. For /ERRORS this
-- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
-- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
-- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
-- is one of these three possibilities). The name given by COMMAND is the
-- corresponding command name to be used to interprete the switches to be
-- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
-- sets the mode so that all subsequent switches, up to another switch
-- with COMMANDS_TRANSLATION apply to the corresponding commands issued
-- by the make utility. For example
-- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
-- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
-- Clearly these switches must come at the end of the list of switches
-- since all subsequent switches apply to an issued command.
-- For the DIRECT_TRANSLATION case, an implicit additional entry is
-- created by prepending NO to the name of the qualifer, and then
-- inverting the sense of the UNIX_SWITCHES string. For example,
-- given the entry:
-- "/LIST -gnatl"
-- An implicit entry is created:
-- "/NOLIST !-gnatl"
-- In the case where, a ! is already present, inverting the sense of the
-- switch means removing it.
subtype S is String;
