Can python pull in feature information such as extents or coordinate system?

I have been putting together a python script to automate metadata creation. For the most part it is just simple find/replace in a word document. I was curious though, is there anything in arcpy which allows us to target a layer and extract information from it, like its extents or coordinate system? I'm not talking about setting it, but finding out what it currently is and having those values written out to text.

Thanks!

Here is how I get the Extent of a layer with arcgisscripting(9.3) where I need to set the extent of the Geoprocessor:

[INDENT]#set fc to a stored layer extlyrDESC = gp.describe(fc)  xmin = extlyrDESC.Extent.XMin ymin = extlyrDESC.Extent.YMin xmax = extlyrDESC.Extent.XMax ymax = extlyrDESC.Extent.YMax   ### sets the actual extent of the Geoprocessor object strExt = str("%f " % xmin + "%f " % ymin + "%f " % xmax + "%f" % ymax) gp.Extent = strExt[/INDENT]
