if i'm simply unaware of such bash features, please feel free to yell at me :)

when working on misc bash scripts, i semi-frequently find the need to do some
sort of string processing along the lines of say changing a string to all
upper case or lower case ... if 'tr' was a bash builtin, then that'd work
with some `echo | tr` magic, but it something like
${foo//[[:lower:]]/[[:upper:]]} would be nice

    There are a couple of extensions available which do case
    conversion. First (naturally) is mine, which is available at:
    <http://cfaj.freeshell.org/shell/bash/loadables/>. Second, is
    William Park's bash extension at:
