+
+<!-- 1. In the line above starting "Parent-Version:", remove the
+ "$Revision...$" from around the revision number,
+ leaving just Parent-Version: and the number. -->
+
+<!-- 2. Replace "baz" with the name of your project.
+ You should be able to do this with search and replace;
+ making sure that the search is case insensitive and
+ that the case of the replacement matches the case
+ of the string found. In Emacs, query-replace will do this
+ when case-fold-search and case-replace are both non-nil
+ and both search and replacement string are given in lower case. -->
+
+<!-- 3. Of course update the actual information according to your project,
+ such as mailing lists, project locations, and maintainer name. -->
+
+<!-- 4. You can use the patch-from-parent script to semi-automate
+ merging future changes to the boilerplate with your file:

+<P>
+Checker is a tool which finds memory errors at runtime. Its
+primary function is to emit a warning when the program reads an
+uninitialized variable or memory area, or when the program accesses an
+unallocated memory area.
+
+<p>
+The Malloc library of Checker is very robust, though a bit slower
+than the usual GNU Malloc. Checker issues warnings when:
+<ul>
+<li> <code>free</code> or <code>realloc</code> is called with a
+ pointer that has not been obtained from <code>malloc</code>,
+ <code>calloc</code>, or <code>realloc</code>.
+<li> <code>free</code> or <code>realloc</code> is called with a
+ pointer that has been previously freed.
+</ul>
+
+<p>
+Checker's Malloc will refrain from reusing a freed block
+immediately; reuse of the block is delayed for some additional number
+of calls to free. This is to catch accesses to the block shortly
+after it has been freed.
+
+<p>
+Checker implements a garbage detector that can be called either in
+your program, by a debugger such as GDB, or on exit from the program.
+The garbage detector displays all the memory leaks along with the
+functions that called <code>malloc</code>.
+
+<h4>Example</h4>
+
+Here's a bogus file <code>example.c</code>:
+
+<pre>
+ #include <stdlib.h>
+
+ int
+ main ()
+ {
+ char *zone = malloc (20);
+ char *ptr = NULL;
+ int i;
+ char c;
+
+ c = zone[1]; /* error: read an uninitialized char */
+ c = zone[-2]; /* error: read before the zone */
+ zone[25] = ' '; /* error: write after the zone */
+ *ptr = 2; /* error: use a NULL pointer,
+ must produce a core */
+ }
+</pre>
+
+To compile this example with Checker, simply use
+<code>checkergcc</code> instead of <code>gcc</code>:
+
+<pre>
+% checkergcc -o example example.c
+</pre>
+
+Next, to run the example:
+
+<pre>
+ % ./example
+</pre>
+
+Execution produces these warnings:
