No AC_PROG_TAR?

[narke]

Hi,

I am writing a script.in file that is supposed to finally produce a
script.sh file by automake.  In this script.in, I like to refer the
full path name of two utilities:  sed and tar, hence I use @SED@ and
@TAR@ int my script.in as a place holder.  By add 'AC_PROG_SED‘ in my
configure.ac, I get the @SED@ works for me.  But since there is no
AC_PROG_TAR, I don't know how to make my @TAR@ works.

Can someone please give me a hint?  And, more generally, how to detect
the full path of an external program?

Thanks in advance.
