try perldoc -f use on your box (or www.perldoc.com):
use Module VERSION LIST
use Module VERSION
use Module LIST
use Module
use VERSION
Imports some semantics into the current package
from the named module, generally by aliasing cer-
tain subroutine or variable names into your pack-
age. It is exactly equivalent to
BEGIN { require Module; import Module LIST; }
except that Module must be a bareword.
VERSION may be either a numeric argument such as
5.006, which will be compared to $], or a literal
of the form v5.6.1, which will be compared to $^V
(aka $PERL_VERSION. A fatal error is produced if
VERSION is greater than the version of the current
Perl interpreter; Perl will not attempt to parse
the rest of the file. Compare with "require",
which can do a similar check at run time.
There is tons more infomation of how use/require are simliar/different.
Enjoy. Wolf
