+ * File : $Source: /cvsroot/ijbswa/current/Attic/actions.c,v $
*
* Purpose : Declares functions to work with actions files
* Functions declared include: FIXME
*
* Revisions :
* $Log: actions.c,v $
+ * Revision 1.32.2.6 2006/01/29 23:10:56 david__schmidt
+ * Multiple filter file support
+ *
+ * Revision 1.32.2.5 2005/06/09 01:18:41 david__schmidt
+ * Tweaks to conditionally include pthread.h if FEATURE_PTHREAD is enabled -
+ * this becomes important when jcc.h gets included later down the line.
+ *
+ * Revision 1.32.2.4 2003/12/03 10:33:11 oes
+ * - Implemented Privoxy version requirement through
+ * for-privoxy-version= statement in {{settings}}
+ * block
+ * - Fix for unchecked out-of-memory condition
+ *
+ * Revision 1.32.2.3 2003/02/28 12:52:10 oes
+ * Fixed memory leak reported by Dan Price in Bug #694713
+ *
+ * Revision 1.32.2.2 2002/11/20 14:36:55 oes
+ * Extended unload_current_actions_file() to multiple AFs.
+ * Thanks to Oliver Stoeneberg for the hint.
+ *
+ * Revision 1.32.2.1 2002/05/26 12:13:16 roro
+ * Change unsigned to unsigned long in actions_name struct. This closes
+ * SourceForge Bug #539284.
+ *
+ * Revision 1.32 2002/05/12 21:36:29 jongfoster
+ * Correcting function comments
+ *
+ * Revision 1.31 2002/05/06 07:56:50 oes
+ * Made actions_to_html independent of FEATURE_CGI_EDIT_ACTIONS
+ *
+ * Revision 1.30 2002/04/30 11:14:52 oes
+ * Made csp the first parameter in *action_to_html
+ *
+ * Revision 1.29 2002/04/26 19:30:54 jongfoster
+ * - current_action_to_html(): Adding help link for the "-" form of
+ * one-string actions.
+ * - Some actions had "<br>-", some "<br> -" (note the space).
+ * Standardizing on no space.
+ * - Greatly simplifying some of the code by using string_join()
+ * where appropriate.
+ *
+ * Revision 1.28 2002/04/26 12:53:15 oes
+ * - CGI AF editor now writes action lines split into
+ * single lines with line continuation
+ * - actions_to_html now embeds each action name in
+ * link to chapter
+ * - current_action_to_text is now called current_action_to_html
+ * and acts like actions_to_html
+ *
+ * Revision 1.27 2002/04/24 02:10:31 oes
+ * - Jon's patch for multiple AFs:
+ * - split load_actions_file, add load_one_actions_file
+ * - make csp->actions_list files an array
+ * - remember file id with each action
+ * - Copy_action now frees dest action before copying
+ *
* Revision 1.26 2002/03/26 22:29:54 swa
* we have a new homepage!
