   In the fc format objects are described by four fields: struct,
behav, logic and hook. struct stands for structural, behav for
behavioral and logic for logical information. hook is used to attach
additional information to objects (like color, position, ...).

   Graphic objects can be labeled according to the four previous
types. Each graphic object has a default label type: struct for box
and vertex, behav for edge, port and web. The edge are multiple
labelled. The <Label>:<Create/Edit Default> menu command is used to
enter objects default label and The <Label>:<Create/Edit All> menu
command to enter the 4 labels. The label edition window accept epoch
like commands. Label fonts and foregrounds depend on both the types of
the label and the object it labels, see <Help>:<Attributes>:<Foregound>
menu. The created composed name will be bufferize in the edition window.

   <Label>:<Bufferize> allow you to bufferize an existing label by
clicking into (it takes also into accoumpt the others 3 fields of the
corresponding objects), next time you label an unnamed object this
label will appear in the edition window.

   <Label>:<Reedit> allow you to edit an existing label:
1- select the <Label>:<Reedit> menu button
2- click on a label
3- edit it in the edition window


Show/Hide Label :
-----------------

  You can show or hide labels depending of label type or globally. For
this, you have 5 walking menus, one for each label type and a global
one. These menus contain 3 functions: the <Show/Hide> function is
applied on the clicked objects (and will work on all the selection if
object is itself selected), the <Show All> and the <Hide All> are
applied on all objects (selected or not).

   <Label>:<Show Label/Object> hilight labels of the objects you click
on, or object of the label you click on.
