+ViewDraw to Xschem importer script
+
+This directory contains a set of test example schematics to be translated into xschem
+the translate.sh script does all the translations, just run it:
+ ./translate.sh
+
+translated xschem files will be in xchem_lib/ directory.
+the xschemrc file in current directory sets up the library paths
+including the xschem_lib directory with translated schematics/symbols.
+Run xschem in current directory so it will set up correctly and find the translated schematics.
+Example:
+ ./xschem xschem_lib/dti_28hc_6p5t_40_ffqx1.sch
+
+files are translated one by one by the viewdraw_import.awk script, it is used as follows:
+
+ ./viewdraw_import.awk xschem_lib /path/to/viewdraw/schematic.1 > /path/to/xschem/schematic.sch
+or:
+ ./viewdraw_import.awk xschem_lib /path/to/viewdraw/symbol.1 > /path/to/xschem/symbol.sym
+
+the first parameter to viewdraw_import.awk is the file to be processed, the second argument
+is the xschem library (directory) that instances will use to reference symbols, i am
+putting all xschem translated objects into xschem_lib/

+
+ViewDraw (and descendents) Schematic Parser
+==========================================
+
+As best I (Patrick Yeon) can tell, ViewDraw has been associated with ViewLogic,
+Innoveda Corp., and now with Mentor under their ePD and DxDesigner tools.
+The format, extended as needed, still shows up in some places in the latest
+version of DxDesigner I have seen, even though the iCDB is meant to be the
+project database.
+
+
+The work to understand the format is based off Stuart Brorson and Steven
+Salkow's earlier "ViewDraw File Formats" documentation, with Patrick Yeon
+working out further extended details based on ViewDraw output files strewn
+about online.
+
+Current Status
+--------------
+The parser can make a decent attempt at parsing schematic and symbol data
+from old versions (schematic files with V 51, symbol files with V 50 or 51,
+that I've seen).
+It has no way to stitch together multi-page designs, and some details fall
+through the cracks because they haven't been worked into the upverter
+format (yet).
+
+This parser has been developed with the
+[ml50x design files](http://www.xilinx.com/support/documentation/boards_and_kits/ml50x_schematics.zip)
+
+Bugs, Omissions, and other Brokeness
+------------------------------------
+At the moment, probably a fair number.
+* A few features of the ViewDraw format couldn't be fit into the upverter
+output format yet: part flipping and re-scaling, at least
+
+Todo
+----
+In no particular order:
+* Harden up against invalid input
+* Work is likely required around pin numbering/naming
+* Nets should be streamlined so that they use a minimum of points
+* Test, test, test.
+
+How To Help
+-----------
+I no longer have access to DxDesigner, so any design output to help shore up
+the understanding of this format would be helpful,
+especially if it is not currently handled properly or completely by the code.
+ViewDraw output from other tools/versions would also be helpful.
+
+Further Notes
+-------------
+From a helpful viewdraw.ini, suspect this is about the `Q` command:
+
+```
