.SH SYNOPSIS

.SH DESCRIPTION
.B Javel
is a java bytecode disassembler and dependency maker.
Depending on the options, it can output some portions of the
disassembled code of the specified files to the standard output.
.B Javel
can also write the dependencies of the specified files in a format
suitable for usage with 'make' or other makefile utilities.
.SH OPTIONS
.TP
.B \-b
For compatibility with javap only. Ignored.
.TP
.B \-c
Disassemble bytecode in methods. If the source code was compiled with
a debug option and contains a local variables table, then each
opcode with access to local variable and/or parameters is displayed
along with the real variable name; otherwise only the index is displayed.
.TP
.B \-help
Display a short usage message. All others options are ignored.
.TP
.B \-l
Ouput line number information. Only available when the -c option is set.
If the class file contains source file information, then
.B javel
tries to load the source file in the current directory and display, along with
the line number, the corresponding line.
.TP
.B \-public
Show only public classes & members.
.TP
.B \-protected
Show only public and protected classes & members.
.TP
.B \-package
Show only public, protected and package classes & members.
.TP
.B \-private
Show all classes & members.
.TP
.B \-s
Print internal type signatures. Ignored.
.TP
.B \-verbose
Print code size, stack size, locals and arguments size for each method.
.TP
.B \-classpath <path>
For compatibility with javap only. Ignored.
.TP
.B \-depend
Output depend information. All others options are ignored if this option
is specified.

.SH EXAMPLE
To output the (almost) orinal version of all methods and members
of the compiled java class
.I Brol.class
on standard output, you can type:

	javel -c -verbose -private Brol.class

To output dependencies of all class files in the
.I src
directory to the file
.I depend.mk
, you can type:

	javel -depend src/*.class > depend.mk

.SH BUGS
The float or double conversion during the compilation from java source code
to class file allows some precision loss on some floating point constants.
Due to that, the disassembled float or double constants can be slightly
different from the original constant numeric value.
