<para>
The <command>Eclipse</command> Platform is an open and
 extensible platform for anything and yet nothing in particular. It provides a
 foundation for constructing and running integrated software-development tools.
 The <command>Eclipse</command> Platform allows tool builders
 to independently develop tools that integrate with other people's tools so
 seamlessly you can't tell where one tool ends and another starts.</para>

 <para>When invoked without selecting any particular application, the <command>eclipse</command>
 command will start the <command>Eclipse</command> Platform with the Java Development
 Tools (JDT) functionality enabled and ready to use.</para>

<para>This manual page documents the command-line arguments for the
<command>Eclipse</command> Platform and it is based on the
Runtime Options help item in the <command>Eclipse</command>
<ulink url="#authors" xrefstyle="AUTHORS">online help</ulink><!-- (see xref endterm="authors" linkend="authors" xrefstyle="AUTHORS"></xref> AUTHORS below)-->.</para>

<refsect1 id='platform_options'><title>PLATFORM OPTIONS</title>
<para>  Listed below are the command line arguments processed by various parts of the
<command>Eclipse</command> runtime.
Many of these values can also be specified using System properties either on the command line
using <command>-D VM</command> arguments, by specifying their values in a <filename>config.ini</filename> file or by using a
<filename>&lt;launcher&gt;.ini</filename> file. Using the two latter techniques it is possible to customize
<command>Eclipse</command> without using command line arguments at all.</para>

<para>For each argument in the list, its corresponding System property key is given (in {}). Also
given is the <command>Eclipse</command> runtime layer in which the
command line argument is processed (in ()). </para>

            when passed to the <command>Eclipse</command>, this option is used to customize the

            specified on the executable command line, the executable will
            automatically add the relevant arguments (including the class being
            launched) to the command line passed into Java using the <command>-vmargs</command>
