Description
-----------
A minimal Altium Designer ASCII schematic file containing:
  - 2 components (R1/RES1 resistor, C1/CAP capacitor)
  - Component pins (RECORD=2)
  - Wire segments (RECORD=37)
  - Labels (RECORD=4) for net annotation
  - Ports (RECORD=209) for power/GND symbols
  - One intentionally unsupported record type (RECORD=99)

This file does NOT contain real design data. It is entirely synthetic and
created for the purpose of unit-testing the ZapTrace Altium importer.

Format notes
------------
The pipe-delimited ASCII format used here mirrors the export format produced
by Altium Designer when saving schematics as ASCII text. Real binary .SchDoc
files use OLE Compound Document (CFB) format; the ASCII subset is documented
in the Altium scripting SDK.
