+<h2>ACL FORMAT</h2>
+
+<p>The format of an ACL is one or more ACL entries separated by either spaces,
+commas or newlines. An ACL entry is one of the following:
+<p><pre>
+
+REVISION:&lt;revision number&gt;
+OWNER:&lt;sid or name&gt;
+GROUP:&lt;sid or name&gt;
+ACL:&lt;sid or name&gt;:&lt;type&gt;/&lt;flags&gt;/&lt;mask&gt;
+</pre>
+
+<p>The revision of the ACL specifies the internal Windows NT ACL revision for
+the security descriptor. If not specified it defaults to 1.
+<p>The owner and group specify the owner and group sids for the object. If a
+SID in the format <code>S-1-x-y-z</code> is specified this is used, otherwise
+the name specified is resolved using the server on which the file or
+directory resides.
+<p>ACLs specify permissions granted to the SID. This SID again can be
+specified in <code>S-1-x-y-z</code> format or as a name in which case it is resolved
+against the server on which the file or directory resides. The type, flags
+and mask values determine the type of access granted to the SID.
+<p>The type can be either 0 or 1 corresponding to ALLOWED or DENIED access to
+the SID. The flags values are generally zero for file ACLs and either 9 or
+2 for directory ACLs. Some common flags are:
+<p><pre>
+
+#define SEC_ACE_FLAG_OBJECT_INHERIT 0x1
+#define SEC_ACE_FLAG_CONTAINER_INHERIT 0x2
+#define SEC_ACE_FLAG_NO_PROPAGATE_INHERIT 0x4
+#define SEC_ACE_FLAG_INHERIT_ONLY 0x8
+</pre>
+
+<p>The mask is a value which expresses the access right granted to
+the SID. It can be given as a hexadecimal value or by using one of the
+following text strings which map to the NT file permissions of the same
+name.
+<p><dl>
+<p><p></p><dt><strong></strong><dd> <code>R</code> Allow read access
+<p><p></p><dt><strong></strong><dd> <code>W</code> Allow write access
+<p><p></p><dt><strong></strong><dd> <code>X</code> Execute permission on the object
