[mapserver-users] how to get a sub-map of a map(shapefile)?

[wzhu at cert.ucr.edu]

HI, 

 I am wondering if anybody knows a tool to get a sub-map of a map. For example,
I need to get a small map around some location instead of a whole big map(Using
whole big map will be time consuming). Thanks a lot.
