+OVERVIEW OF MAIN_CHUNK
+
+We start out with a lot of housekeeping, especially with respect to
+perl and ghostscript: if we are going to use the built-in versions,
+then the search path and other environment variables must be set or
+unset to make these findable and working right.
+
+Next we compose an ARGV table for os.spawn, unless the script turns
+out to be a [tex]lua script; see further down this comment block.
+
+The parameter table ARGV can have the following elements (see the
+luatex manual on os.exec and os.spawn):
+
+- ARGV[0]: the full path to the interpreter
+- ARGV[1]: the filename part of the interpreter. The interpreter choice
+ depends on the detected script extension and also on gui mode.
+- ARGV[2]: progfulname, the full path to the script
+- ARGV[3]: argline, i.e. the unparsed arguments for the script.
+ This is normally the last argument passed to runscript.tlu.
+ See the actual code for when this is not the case.
+
+ARGV[0] gets priority over ARGV[1] if it is present.
+
+After everything has been set up, a call os.spawn(ARGV) runs the
+right program with the right arguments.
+
+But in case the script to be run is a texlua script, we run the script
+in the current texlua process using the dofile function. The original arg
+argument table may have been modified before then.
+
+Some variables:
+
+- ARGV, see above
+- arg, the texlua argument table of runscript.tlu
+- progname, the name under which [w]runscript.exe was called
+- progfullname, the full path of the script to be run. This variable
+ is introduced only after some special cases have been dealt with.
+- argline, unparsed arguments to the script; may get modified
