Leif Hedstrom commented on TS-2469:
-----------------------------------
As [[email protected]] points out, why remove libreadline support? There's no
violation to use GPL libraries, as long as it's not a hard requirement. And the
alternative, which we already supported, is e.g. "edit" or "editline".
One suggestion would be to just reorder the line, such that we prefer those two
over libreadline, e.g.
{code}
diff --git a/build/ax_lib_readline.m4 b/build/ax_lib_readline.m4
index 1af80b2..e4d09a6 100644

> libreadline is gpl licensed which is infectious. libedit is a free
> alternative, and is already supported in the configure scripts so libreadline
> support should be removed.
> it seems traffic_shell is the only thing using libreadline/libedit currently.
