说明
pic is a troff preprocessor for drawing diagrams. It converts textual descriptions into troff drawing commands. Diagrams use geometric primitives: boxes, circles, lines, arrows. Positioning is relative or absolute. Objects connect with lines and arrows. Labels and text annotate elements. The language supports macros and variables. Complex diagrams build from reusable components. Output integrates with groff/troff document processing. Pic diagrams embed in technical documents.
