But what _is_ "the core functionality".
The Single Unix Specification can be browsed on-line.
There is no part of it labelled "core"; it's all required
or it isn't AWK. There are weird little gotchas like
File "foo" = '{ prin'
File "bar" = 't 2 }'
awk -f foo -f bar
is legal and is required to act the same as
awk '{ print 2 }'
mawk fails this, and I don't blame it, and I don't really _care_.
Is that "core"? Who knows?
Whatever the "core functionality" might be, YOU will have to define
what that "core" is. There's no standard, or even common, sublanguage.
