dnl this macro has been copied from /usr/share/aclocal/pkg.m4
dnl modified to check only for zziplib. You are advised to use
dnl pgkconfig macro directly instead. It is only installed to
dnl the convenience of software makers who do not want to have
dnl yet another package dependency when building zziplib-based
dnl projects. In general, you can include in your configure.ac
dnl some line like
dnl PKG_CHECK_ZZIPLIB([ZZIP],[0.10.75])
dnl in order to get the two autoconf/automake subst variables
dnl named ZZIP_CFLAGS and ZZIP_LIBS respectivly.

dnl PKG_CHECK_ZZIPLIB(ZZIP, minversion, action-if, action-not)
dnl defines ZZIP_LIBS, ZZIP_CFLAGS, see pkg-config man page
dnl also defines ZZIP_PKG_ERRORS on error
