 and change some compilation variables. The following dependencies are required:
 - XQuartz: https://www.xquartz.org/releases/XQuartz-2.7.11.html

 The first step is to install XQuartz and then compile Tcl and Tk. Nothing special on compiling these two, but
 we need to specify the X libraries from XQuartz when compiling Tk. Let's use the path
 /usr/local/opt/tcl-tk as destination folder.
 ## Tcl compilation
 Extract the Tcl sources and then go to the unix folder:
 
-cd <extracted-folder>/unix
+`cd <extracted-folder>/unix`  
-./configure --prefix=/usr/local/opt/tcl-tk

 Besides referencing the X libraries, we need to also point to the Tcl/Tk installation path. Let's use a recent
