Runs a specified command for each file in a set of files.

FOR %%variable IN (set) DO command [command-parameters]

  %%variable  Specifies a single letter replaceable parameter.
  (set)      Specifies a set of one or more files.  Wildcards may be used.
  command    Specifies the command to carry out for each file.
  command-parameters
             Specifies parameters or switches for the specified command.

To use the FOR command in a batch program, specify %%%%variable instead
of %%variable.  Variable names are case sensitive, so %%i is different
from %%I.
