+<refsect1><title>INCLUDE AND EXCLUDE LISTS</title>
+
+<para>This application supplies exclude lists via the &gnutar;
+<option>--exclude-from</option> option. This option accepts normal
+shell-style wildcard expressions, using <option>*</option> to match any
+number of characters and <option>?</option> to match a single character.
+Character classes are represented with <option>[..]</option>, which will
+match any of the characters in the brackets. Expressions can be "anchored"
+to the base directory of the DLE by prefixing them with "./". Without this
+prefix, they will match at any directory level. Expressions that begin or
+end with a "/" will not match anything: to completely exclude a directory,
+do not include the trailing slash. Example expressions:
+<programlisting>
+ ./temp-files # exclude top-level directory entirely
+ ./temp-files/ # BAD: does nothing
+ /temp-files # BAD: does nothing
+ ./temp-files/* # exclude directory contents; include directory
+ temp-files # exclude anything named "temp-files"
+ generated-* # exclude anything beginning with "generated-"
+ *.iso # exclude ISO files
+ proxy/local/cache # exclude "cache" in dir "local" in "proxy"
+</programlisting>
+</para>
+
+<para>Similarly, include expressions are supplied to &gnutar;'s
+<option>--files-from</option> option. This option ordinarily does not
+accept any sort of wildcards, but amgtar "manually" applies glob pattern
+matching to include expressions with only one slash. The expressions must
+still begin with "./", so this effectively only allows expressions like
+"./[abc]*" or "./*.txt".</para>
