/**

* Class SCH_LEGACY_PLUGIN
|
||
|
*
|
||
|
* is a #SCH_PLUGIN derivation for loading schematic files created before the new
|
||
|
* s-expression file format.
|
||
|
*
|
||
|
* The legacy parser and formatter attempt to be compatible with the legacy file format.
|
||
|
* The original parser was very forgiving in that it would parse only part of a keyword.
|
||
|
* So "$C", "$Co", and "$Com" could be used for "$Comp" and the old parser would allow
|
||
|
* this. This parser is not that forgiving and sticks to the legacy file format document.
|
||
|
*
|
||
|
* As with all SCH_PLUGINs there is no UI dependencies i.e. windowing calls allowed.
