This script will parse boulderindoorsoccer.com and create an ICS calendar file in the directory where it is executed.
With python installed (I suggest downloading python through anaconda from here) go to the location of the "bis-cal.py" file and type:
python bis-cal.py <team>
where <team> is the name of the team who's calendar you want. The script will also look up teams from a subset of a team name. For example, "Slothy" will generate the calendar for the team "Sooooo Slothy" given that there are no other teams with "Slothy" in their name.
The ICS file can be imported into Google calendars following these instructions.
