ApE has a single dependency, the Tcl/Tk interpreter that must be installed.
See instructions for installing Tcl/Tk on linux:
https://tkdocs.com/tutorial/install.html#install-x11-tcl

In short, you should be able to do:
apt install tk8.6

After installing Tcl/Tk, cd to the ApE Linux folder that you downloaded, then run the ApE.tcl script with the Wish interpreter:
/usr/bin/wish8.6 ApE.tcl

OR
make the ApE.tcl script executable:
chmod +x ApE.tcl

then run the script directly:
ApE.tcl


If you'd like to make a desktop icon for ApE, there is a .desktop file in the Acessory Files directory.
To use that file do three things:
1. make the ApE.tcl script executable (as above):
chmod +x ApE.tcl

2. Edit ApE.desktop to change ~/bin/ApE to the location that you are installing ApE (you have to edit two lines at the end).

3. copy ApE.desktop to 
~/.local/share/applications/ApE.desktop
OR
/usr/share/applications/ApE.desktop


If you'd like to associate add MIME types associated with ApE, there is an xml file, ape-mime-type.xml in the Acessory Files directory.
To use that file do three things:
1. Edit the xml file to have the glob pattern for the files you want to assocate.

2. Move or copy the xml file to ~/local/share/mime/packages/ for a sinle user or /usr/share/mime/packages for system-wide use

3. Call update-mime-database ~/.local/share/mime for a sinle user or 
update-mime-database from the system account for system-wide use.
