 %description
-This package contains a Base64 encoder/decoder and a quoted-printable
-encoder/decoder. These encoding methods are specified in RFC 2045 - MIME
-(Multipurpose Internet Mail Extensions).
+perl-MIME-Base64 is a Perl module that provides encoding and decoding
+functions for the Base64 encoding scheme. This encoding is commonly used
+for email attachments, as well as other data transmission applications
+where binary data needs to be transmitted over text-based channels.
+The module provides a simple interface for encoding and decoding data using
+Base64, making it easy to integrate into Perl scripts and other applications.
