In some environments any requirement for an executable as single file may be awkward.
In a Unix-like environment an option could be to concatenate a shell script stub followed
by the contents of some kind of archive.  However, to execute the program, the script might
have to uncompress the script in a temporary location, which is possible, but could be expensive.

FWIW: I was surprised to find out you can concatenate a shell script with the .jar
(Java Archive) file, and have the shell script call something like 'exec java -jar $0'.
I.e. the java command can skip the shell-script preamble when looking for the jar contents.
So that may be a possible approach for Java and other JVM-based implementations.
