What is this directory "$(brew --prefix)"? (homebrew)

Hello,

I installed the package manager called homebrew a few days ago. Everything seems to be working fine but today I've just noticed this funny looking directory $(brew --prefix). I'm not sure if I made a mistake and duplicated this directory from somewhere else, or if it's suppose to be there.

Code:

MBP:~ m$ pwd
/Users/m
MBP:~ m$ ls -ltr
total 40
  ...other files and dirs
drwxr-xr-x   8 m     staff   272 Jun  8 03:49 $(brew --prefix)
MBP:~ m$ ls $(brew --prefix)
Cellar    Library   README.md bin       etc       include   lib       share

Executing the the brew commands "Display the real path to your Homebrew prefix" and "Display the real path to your Homebrew Cellar

Code:

MBP:~ m$ brew --prefix
/usr/local
MBP:~ m$ brew --cellar
/usr/local/Cellar

So Looking at this, is /Users/m/$(brew --prefix) a redundant duplicate I somehow made which I can now delete? Or is that dollar sign in front of a directory name meaning something else I am not understanding?

Thanks, Michelle

smode2

SMODE2(1)								FSF								 SMODE2(1)

NAME

       mode2, smode2, xmode2 - shows the pulse/space length of infrared signals

SYNOPSIS

       smode2 [options]

DESCRIPTION

       The  main purpose of these programs is to check operation of your home-brew LIRC receiver hardware and to see the IR waveform of the remote
       controller without an expensive oscilloscope. Very useful for debugging. Of course this program won't work with hardware that  decodes  the
       signals itself like e.g. TV cards or the Irman.

       smode2  uses  the  svgalib to show the IR waveform in a graphical representation. The time division is variable from 1 ms/unit to extremely
       high values (integer type) but there is no point increasing this value above 20 ms/unit, because one pulse is about 1 ms. This kind of pre-
       sentation is much more exciting than the simple pulse&space output showed by mode2.

       -d --device=device
