+# We sleep (by default) for 0 seconds after each command but one can set that to
+# a different value so that it's easier for them to read what is being done. For

+# If you need to pass a different compiler, say because your compiler is clang,
+# you can use the CC environmental variable like:
+#
+#   CC=gcc ./try.sh
+#
+# This will be passed to compile.sh.

+# If CC is empty (not specified) it defaults to 'cc'. After it is set to either

+# default 'cc') CC var to make use of it.

+# If CC is a path it will use that; otherwise it will let the script find the
+# path via the shell. This is useful for this entry in particular because in
+# macOS /usr/bin/gcc is actually clang and some of the versions of this entry
+# will not compile with clang due to defects. Getting any version to compile

+# example in macOS /usr/bin/gcc is actually clang) you can at least get some
