   db.dropcol drops a column from an attribute table. If the -f force flag
   is not given then nothing is removed, instead a preview of the action
   to be taken is printed.

ÐÐ ÐÐÐЧÐÐÐЯ

   db.dropcol is a front-end to db.execute to allow easier usage with a
   special workaround for the SQLite driver to support column drop.

ÐÐ ÐÐÐРЫ

   Dropping a column (Spearfish):

# work on own copy
g.copy vect=roads,myroads
db.describe -c myroads

# only shows what would happen:
db.dropcol myroads column=label

# actually drops the column
db.dropcol -f myroads column=label

db.describe -c myroads
