`tempo' templates are used for each category of javadoc line.  The
following templates are currently defined and fully customizable (see
`tempo-define-template' for the different items that can be used in a
tempo template):

- - `jde-javadoc-author-tag-template'
- - `jde-javadoc-describe-class-template'
- - `jde-javadoc-describe-constructor-template'
- - `jde-javadoc-describe-interface-template'
- - `jde-javadoc-describe-method-template'

- - `jde-javadoc-exception-tag-template'
- - `jde-javadoc-param-tag-template'
- - `jde-javadoc-return-tag-template'
- - `jde-javadoc-version-tag-template'

For example if you customize `jde-javadoc-describe-class-template'
with the following value:

'(\"* \" (P \"Class description: \"))

you will be asked to enter the class description in the minibuffer.

;;
;; Revision 1.25  2002/10/11 05:53:22  paulk

;; Removes carriage returns.
;;
;; Revision 1.21  2002/06/22 06:25:26  paulk
;; Adds jde-javadoc-check-undeclared-exception-flag option. Thanks to David Ponce.
;;
;; Revision 1.20  2001/12/14 03:17:50  paulk
;; jde-javadoc-nonterminal-at-line preserves current tokens when the
;; lexer fails (when there is an unclosed block or an unterminated
;; string for example). This enhancement works only with semantic 1.4
;; beta 13 (and above). With older versions
;; jde-javadoc-nonterminal-at-line continues to work as previously.
;; Thanks to David Ponce.
;;
;; Revision 1.19  2001/08/06 05:25:21  paulk
;; jde-javadoc-parse-tag-values now removes the brackets from
;; VALUE-STRING when VALUE-KEY is 'name.  This fixes checker error when
;; it tries to match an array name in javadoc comments and in argument
;; list. Thanks to David Ponce.
;;
;; Revision 1.18  2001/05/19 02:36:00  paulk
;; Updated to support semantic 1.4. Thanks to David Ponce.
;;
;; Revision 1.17  2001/01/27 05:42:07  paulk
;; Enhancements from David Ponce:
;;
;; - Improved `jde-javadoc-start-tag-regexp' and
;;   `jde-javadoc-end-tag-regexp' regular expressions which fix little
;;   problems when parsing javadoc tags.  These regexps enforce the
;;   following rule (from JDK 1.3 documentation "javadoc - The Java
;;   API Documentation Generator" - Chapter "DOCUMENTATION COMMENTS" -
;;   "Standard and in-line tags":
;;
;;
;;   "[...] a standard tag must appear at the beginning of a line,
;;   ignoring leading asterisks, white space and comment separator
;;   (/**). This means you can use the @ character elsewhere in the
;;   text and it will not be interpreted as the start of a tag. If you
;;   want to start a line with the @ character and not have it be
;;   interpreted, use the HTML entity @. [...]"
;;
;;
;; - `jde-javadoc-checker-report-mode' now turns on `font-lock-mode'.
;;   This is useful in XEmacs which don't have a
;;   `global-font-lock-mode'.
;;
;;
;; - Filling of messages in `jde-javadoc-checker-show-report' now
;;   works with XEmacs too.

;; Miscellaneous bug fixes and minor enhancements.
;;
;; Revision 1.14  2000/10/25 03:11:57  paulk
;; Enhancements from David Ponce:
;;
;; * It is now possible to check javadoc comments only for tokens with
;;   a specified access level. The new `jde-javadoc-checker-level'
;;   option defines the accessibility level to check.
;;
;;   Only 'type, 'function or 'variable tokens with this level will be
;;   checked. The level is defined to be consistent with the javadoc
;;   show options. That is:
;;
;;   - - public    - check only public classes and members.
;;   - - protected - check only protected and public classes and
;;                   members. This is the default.
;;   - - package   - check only package, protected, and public classes
;;                   and members.
;;   - - private   - check all classes and members.
;;
;;   If a token is included in other ones its access level is the
;;   lowest one found in the hierarchy.
;;
;;   Using `jde-javadoc-checkdoc-at-line' it is always possible to
;;   check any token regardless of its access level.
;;
;; * Changed '[u]-update' action by more appropriate '[f]-try to fix'
;;   in the checker report dialog.
;;
;; * Changed message "Invalid tag order, must be ..." by
;;   "Recommended tag order is ...".
;;
