+Environment Variables
+=====================
+
+Description
+-----------
+This patch loads the name of the terminal emulator to be used as `termcmd`
+from the environment variable `TERMINAL` using `getenv(3p)`.
+It may be set as follows:
+
+`$ export TERMINAL="$(which st)"`
+
+The environment variable to use may be changed with the `TERMINAL_ENVVAR`
+preprocessor macro.
+A similar patch could be created for the `dmenucmd`.
