+Sequential Function Chart (SFC) describes the behaviour of a
+control program. It is derived from Petri Nets and GRAFCET.
+This package contains a set of symbols that simplifies the
+drawing of SFC diagrams with emphasis in readability and in
+agreement with the international standard IEC 61 131-3. It
+extends the TikZ-library circuits which defines general keys
+for creating circuits. All graphic elements of SFC are
+supported by tikz-sfc: steps (normal and initial),
+transitions, actions and actions qualifiers (with and without
+time duration) are supported. The placement of all actions
+associated with a step is done automatically. Comments can
+also be placed automatically in a suitable location near the
+element they refer to. The final appearance of each element
+can be fine-tuned individually or in group.
