yum provides */uuencode

I always sent to myself files with uuencode. And today I was surprised when I did not find it in one of the systems.
'yum list |grep uuencode' didn't show any package
Then I googled and found advise to install sharutils

 To understand it was enough to issue
 yum provides */uuencode
which found the package with uuencode

sharutils-4.7-6.1.el6.x86_64 : The GNU shar utilities for packaging and unpackaging shell archives
Repo        : rhel6-server-...
Matched from:
Filename    : /usr/bin/uuencode

After 'yum install sharutils' the 'which uuencode' is sucsessful
/usr/bin/uuencode
