procedure Ada_Param_Unix;
------------------------------------------------------------------------------
-- 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.
