It does.

If a script begins with the characters "#!" and the name of a script
interpreter, and has the execute bit set, then it can be executed like any
other program, and the front end can run it the same way the front end
would run any TeX engine.  This is a facility of the operating system,
often called the "shebang" mechanism, and it is transparent to
applications.  There is no need for the front end to know what language
the script is written in, nor how to interpret that language.
