How to add alias for formula ?

How to add an alias for a formula ?

for example: the zeromq formula has an alias zmq
ie. zmq is linked under /usr/local/Library/Aliases
and can do a brew search for zmq and zeromq

but do not understand, how is that done ?
looked at:

• the zeromq formula
• cookbook

wanted to know for, adding an alias for the node formula

right now, we have to remember to, do a brew install node4-lts
but want to install node-lts which will alias node4-lts now
and node6-lts when a new LTS is released in a few months

For aliases you create a symlink in the Aliases directory, pointing at the formula you want to alias: https://github.com/Homebrew/homebrew-core/tree/master/Aliases

But I can't see any way to have a symlink automatically change where it points to; from node4-lts to node6-lts in your case.

ok. thanks @dunn for answering

one more question,
where does the zeromq formula create an alias for zmq ?
do not see anything for alias in the zeromq formula

[dunn]

It doesn't. We create aliases manually.
