procedure Ada_Param_Unix is
------------------------------------------------------------------------------
-- Command line arguments:
--
-- -f <name> - File - Specifies an input file name
-- -n - Normalize - Special switch for use with the "patch" program.
-- All "--//" strings are removed from the source.
-- -x - Extension - Indicates that the input file's extension is
-- to be make all lowercase on output.
-- -p <string> - Parms - Specifies additional/different parameter
-- values to use,
-- eg. "Foo,Bar=>False,Gorp=>Foo|Bar"
--
-- Used to run some Ada unit through the parameterizer. We run through the
-- unit looking for --/if statements and we (un)comment(out) anything that
-- isn't "true" according to the default parameter settings (as modified by
-- the -p settings, if any).
--
-- Processing steps:
--
-- 1) Read the file looking for structured comments. Produce a temporary
-- output file called ada.param.tmp.
-- 2) Pick an output filename. If -x was not given then the output filename
-- is the same as the input filename. If -x was given then the output
-- filename is the same as the input filename except that all letters
-- in the extension will be make lowercase.
-- 3) If a file with the output filename already exists then compare it
-- to the temporary output file. If they are identical then delete
-- the temporary file and exit successfully.
-- 4) Copy the temporary file to the output filename and then delete the
-- temporary file.
