       Wallet::ACL::Krb5::Regex is the wallet ACL verifier used to verify ACL lines of type "krb5-regex".  The
       value of such an ACL is a Perl regular expression, and the ACL grants access to a given Kerberos
       principal if and only if the regular expression matches that principal.

       malformed krb5-regex ACL
           The ACL parameter to check() was a malformed Perl regular expression.

       no principal specified
           The PRINCIPAL parameter to check() was undefined or the empty string.

       no ACL specified
           The ACL parameter to check() was undefined or the empty string.

new()
           Creates a new ACL verifier.  For this verifier, there is no setup work.

       check(PRINCIPAL, ACL)
           Returns true if the Perl regular expression specified by the ACL matches the PRINCIPAL, false if not,
           and undef on an error (see "DIAGNOSTICS" below).

       error()
           Returns the error if check() returned undef.
