   An EXE (or self executable) file consists of 3 parts:
   <ul class="simplelist">
    <li class="member">
     The <em>stub</em> (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. <em>main::main</em>)

   To obtain a suitable stub you can compile php_embed-based stub <var class="filename">phpe.c</var>
