.SH DESCRIPTION
.IX Header "DESCRIPTION"
Hash::Case::Lower extends Hash::Case, which lets you play various
trics with hash keys. In this implementation, the fake hash is case
insensitive and the keys stored in lower\-case.

.IX Item "tie %hash, 'Hash::Case::Lower', [$values,] %options"
Define \f(CW%hash\fR to have only lower\-cased keys.  The hash is initialized with
the \f(CW$values\fR, specified as ARRAY (with key\-value PAIRS) or HASH.
Currently, there are no \f(CW%options\fR defined.
