 It is also capable of distinguish #define used for specifying a Linux
 ioctl.
 
-The EXCEPTIONS_FILE contain two types of statements: B<ignore> or B<replace>.
+The EXCEPTIONS_FILE contain two rules to allow ignoring a symbol or
+to replace the default references by a custom one.
 
-The syntax for the ignore tag is:
-
-=over 8
-
-ignore B<type> B<name>
-
-=back
-
-The B<ignore> means that it won't generate cross references for a
-B<name> symbol of type B<type>.
-
-The syntax for the replace tag is:
-
-=over 8
-
-replace B<type> B<name> B<new_value>
-
-=back
-
-The B<replace> means that it will generate cross references for a
-B<name> symbol of type B<type>, but, instead of using the default
-replacement rule, it will use B<new_value>.
-
-For both statements, B<type> can be either one of the following:
-
-=over 8
-
-=item B<ioctl>
-
-The ignore or replace statement will apply to ioctl definitions like:
-
-#define	VIDIOC_DBG_S_REGISTER 	 _IOW('V', 79, struct v4l2_dbg_register)
-
-=item B<define>
-
-The ignore or replace statement will apply to any other #define found
-at C_FILE.
-
-=item B<typedef>
-
-The ignore or replace statement will apply to typedef statements at C_FILE.
-
-=item B<struct>
-
-The ignore or replace statement will apply to the name of struct statements
-at C_FILE.
-
-=item B<enum>
-
-The ignore or replace statement will apply to the name of enum statements
-at C_FILE.
-
-=item B<symbol>
-
-The ignore or replace statement will apply to the name of enum statements
-at C_FILE.
-
-
-For replace statements, B<new_value> will automatically use :c:type:
-references for B<typedef>, B<enum> and B<struct> types. It will use :ref:
-for B<ioctl>, B<define> and B<symbol> types. The type of reference can
-also be explicitly defined at the replace statement.

-
-Ignore a #define _VIDEODEV2_H at the C_FILE.
-

-
-ignore symbol PRIVATE
-
-=over 8
-
-On a struct like:
-
-enum foo { BAR1, BAR2, PRIVATE };
-
-It won't generate cross-references for B<PRIVATE>.
-

-
-replace symbol BAR1 :c:type:`foo`
-replace symbol BAR2 :c:type:`foo`
-
-=over 8
-
-On a struct like:
-
-enum foo { BAR1, BAR2, PRIVATE };
-
-It will make the BAR1 and BAR2 enum symbols to cross reference the foo
-symbol at the C domain.
