+Connects to signals available with SylPlugin object (obtained inside library).
+The specification of callback functions that receive signals is similar to
+that of normal GObject.
+Refer to the signals list for available signals.
 -------------------------------------------------------------------------
 void syl_plugin_signal_disconnect(gpointer func, gpointer data);
 
+Disconnects signals connected by syl_plugin_signal_connect().
 -------------------------------------------------------------------------
 void syl_plugin_signal_emit(const gchar *name, ...);
 
+Emits SylPlugin object signals.
 -------------------------------------------------------------------------
 gint syl_plugin_init_lib        (void);
 
+Initializes the libsylpheed-plugin-0 library.
 -------------------------------------------------------------------------
 gint syl_plugin_load            (const gchar *file);
 
+Loads plug-in DLL files into memory.
 -------------------------------------------------------------------------
 gint syl_plugin_load_all        (const gchar *dir);
 
+Loads plug-in DLL files in the specified directory into memory.

 void syl_plugin_unload_all      (void);
 
+Unloads all loaded plug-ins.
 -------------------------------------------------------------------------
 GSList *syl_plugin_get_module_list      (void);
 
+Obtains the list of plug-ins loaded into memory.
+It returns the list of pointers to GModule struct.
+The list is obtained by the library internally, so it must not be freed.
 -------------------------------------------------------------------------
 SylPluginInfo *syl_plugin_get_info      (GModule *module);
 
+Obtains plug-in information. The information is returned as SylPluginInfo
+struct.
 -------------------------------------------------------------------------
 gboolean syl_plugin_check_version       (GModule *module);
 
+Compares plug-in interface versions and checks if the plug-in is compatible.
+Returns TRUE if the version matches, FALSE otherwise.
 -------------------------------------------------------------------------
 gint syl_plugin_add_symbol              (const gchar *name, gpointer sym);
 
+Registers symbol name and pointer value related to it to the library.
 -------------------------------------------------------------------------
 gpointer syl_plugin_lookup_symbol       (const gchar *name);
 
+Searches symbol registered by syl_plugin_add_symbol() and returns its
+pointer value.

 void plugin_load(void)

 void plugin_unload(void)

 SylPluginInfo *plugin_info(void)
 
+Fuction to return struct which stores plug-in information to Sylpheed.
+It normally returns pointer to static struct.
 -------------------------------------------------------------------------
 gint plugin_interface_version(void)
 
+Function to return plug-in API interface version to Sylpheed.
+A plug-in normally returns constant value SYL_PLUGIN_INTERFACE_VERSION.
+Sylpheed compares this value with its own value and checks if it is
+compatible. Sylpheed's plug-in interface version must be equal to or greater
+than the plug-in's plug-in interface verson. If the major versions of the
+interface version differ, they are treated as incompatible.

+Ex.1: Sylpheed plug-in interface version: 0x0102
+      A plug-in plug-in interface version: 0x0100: OK
+Ex.2: Sylpheed plug-in interface version: 0x0102
