[Freegis-list] How can I "clip" shapefiles to a box-shaped subset without using the ESRI ArcMap tool?

[Murray Brown]

Our marine data training program (www.oceanteacher.org) tries to avoid necessary use of commercial software, and so far we've been able to stay nearly ESRI-free.  But the one Arc tool that we still find necessary is the clip function that cuts a shapefile down to the borders defined by a second shapefile.  In our case, the second shapefile is almost always a simple rectangular box (area of interest).

Does anybody know a free, stand-alone program (hopefully a binary executable) that can do this also?

Thanks in advance for any help.
