"""gen_pattern.py
To run:
-c 10 -r 12 -o out.svg
-T type of pattern, circles, acircles, checkerboard
-s --square_size size of squares in pattern
-u --units mm, inches, px, m
-w page width in units
-h page height in units
Usage example:
python gen_pattern.py -o out.svg -r 11 -c 8 -T circles -s 20.0 -R 5.0 -u mm -w 216 -h 279
-o, --output - output file (default out.svg)
-r, --rows - pattern rows (default 11)
-c, --columns - pattern columns (default 8)
-T, --type - type of pattern, circles, acircles, checkerboard (default circles)
-s, --square_size - size of squares in pattern (default 20.0)
-R, --radius_rate - circles_radius = square_size/radius_rate (default 5.0)
-u, --units - mm, inches, px, m (default mm)
-w, --page_width - page width in units (default 216)
-h, --page_height - page height in units (default 279)
-H, --help - show help
