Input and output files
======================

   A `gcj' command is like a `gcc' command, in that it consists of a
number of options and file names.  The following kinds of input file
names are supported:

`FILE.java'
     Java source files.

`FILE.class'
     Java bytecode files.

`FILE.zip'
`FILE.jar'
     An archive containing one or more `.class' files, all of which are
     compiled.  The archive may be compressed.

`@FILE'
     A file containing a whitespace-separated list of input file names.
     (Currently, these must all be `.java' source files, but that may
     change.)  Each named file is compiled, just as if it had been on
     the command line.

`LIBRARY.a'
`LIBRARY.so'
`-lLIBNAME'
     Libraries to use when linking.  See the `gcc' manual.

   You can specify more than one input file on the `gcj' command line,
in which case they will all be compiled.  If you specify a `-o FILENAME'
option, all the input files will be compiled together, producing a
single output file, named FILENAME.  This is allowed even when using
`-S' or `-c', but not when using `-C'.  (This is an extension beyond
the what plain `gcc' allows.)  (If more than one input file is
specified, all must currently be `.java' files, though we hope to fix
this.)
