/*

Simple wrapper program to allow people to suid to their own user id.
Version 2.0b

Directions:

0) Edit the text below for the_file file name variable.

1) Compile this C program (use cc if you don't have gcc):

     gcc -o wrap_mgr.o wrap_mgr.c

2) Set permissions on the wrapper so it runs under your id:

     chmod 555 wrap_mgr.o
     chmod a+s wrap_mgr.o

3) Manager.cgi 3.1+ will detect the wrapper and use it automatically if it
   is properly placed in the same directory.
