Description: glSPI - compact, fast, simple viewer for DXF/EMF/GBR files.

A system should have OpenGL installed to use the program.
AutoCAD Drawing Exchange (DXF) format is ASCII mode, 2D.
GBR is PCB Gerber data file, with some support RS-274X aperture.
EMF MS Windows Enhanced Metafile is for drawings only - no bitmap.
Due to lack of user feedback - raster mode of the program is uncertain now.

Beta note: only files,placed into and the same direcory(or to subdirectory) with glSPI are observed.

Don't launch glSPI from a directory with deep file tree (/ or C:\) - walking thru it may take time!!!

Open submenu of the main menu shows list of DXF/EMF/GBR files, occured in working dir(or subdire) .
Command line file feeding is also supported.
DXF/EMF/GBR files should have .DXF, .EMF, .GBR extensions.

Dragging with left mouse button pressed is a selection tool for Zoom-In command.
Left button click and move is a paning tool.
