<para>
An EXE (or self executable) file consists of 3 parts:
<simplelist>
<member>
The stub (executable code, e.g. a compiled C program) that loads PHP
interpreter, bcompiler extension, stored Bytecodes and initiates a call
for the specified function (e.g. main) or class method (e.g. main::main)
</member>
<member>The Bytecodes (uncompressed only for the moment)</member>
<member>The bcompiler EXE footer</member>
</simplelist>
</para>
<para>
To obtain a suitable stub you can compile php_embed-based stub phpe.c
located in the examples/embed directory on bcompiler's CVS.
