-By default, runawk will invoke whatever binary is present or linked from /usr/bin/awk. You can also configure it differently; for example, this will build a runawk that always invokes BusyBox awk, even if another awk is linked from /usr/bin/awk:
+The displayed values for the make variables are the defaults, and can be omitted if you're happy with those values.
+AWK can also be set to /bin/busybox; in that case, the runawk binary will invoke busybox with an "awk" argument. This permits building runawk so that it always invokes BusyBox awk, even if another awk is linked from /usr/bin/awk.

That is, the -f option can't be mixed with providing an awk script directly on the command line, rather than in a separate file. Gawk and runawk's -e option provide a way to do this:
- awk -f library.awk -e '...awk script...' argv1 ...
+ runawk -f library.awk -e '...awk script...' argv1 ...
Runawk also knows how to handle gawk's --exec option. See the source for details.
