[Remind-Fans] Problems Aliasing Remind Output Using the Today Variable

[Justin Alcorn]

The problem is that the alias commands are run as part of your shell 
startup, and the command

`(echo 'banner %'; echo 'msg [trigger(today()+2)]') | remind -`

is run during shell startup, and the _result_ is used in the alias 
command.  So the date is the day you log in.

You need to find some way to escape the meaning of the `` and have that 
put into the alias.

The easiest way is to forget alias and make them shell scripts in your path.
