/**
 * Information which can be added in a gerber P&P file as attribute of a component.
 *
 * This is only applicable to objects having the TA.AperFunction attribute "ComponentMain"
 * There are specific attributes defined attached to the component by the %TO command
 * %TO.CRot,<angle> The rotation angle of the component.
 *   The rotation angle is consistent with the one for graphics objects.
 *   Positive rotation is counter- clockwise as viewed from the top side, even if
 *   the component is on the board side.
 *   The base orientation of component - no rotation - on the top side is as in IPC-7351.
 *   Components on the bottom side are of course mirrored.
 *   The base orientation on the bottom side is the one on the top side
 *   mirrored around the X axis.
 *
 * %TO.CMfr,<string>     Manufacturer
 * %TO.CMPN,<string>     Manufacturer part number
 * %TO.Cpkg,<string>     Package, as per IPC-7351
 * %TO.CVal,<string>     Value, a string. E.g. 220nF
 * %TO.CMnt,<string>     Mount type: (SMD|TH|Other)
 * %TO.CFtp,<string>     Footprint name, a string. E.g. LQFP-100_14x14mm_P0.5mm
                         This is the footprint name coming from the CAD tool libraries.
 * %TO.CPgN,<string>     Package name, like the JEDEC JEP95 standard.
 * %TO.CPgD,<string>     Package description.
 * %TO.CHgt,<string>     Height, a decimal, in the unit of the file.
 * %TO.CLbN,<string>     Library name.
 * %TO.CLbD,<string>     Library description.
 * %TO.Sup,<SN>,<SPN>    SN is a field with the supplier name.
 *                       SPN is a field with the supplier part name.
