-dnl @synopsis ST_LIB_ARCHIVE([ENABLED-DEFAULT])
-dnl
-dnl This macro figures out what's necessary to link a program against an
-dnl instance of the BSD libarchive package by Tim Kientzle.
-dnl
-dnl See http://people.freebsd.org/~kientzle/libarchive/ for more info.
-dnl
-dnl It exports and substitutes the variables LIBARCHIVE_LIBS, LIBARCHIVE_LDFLAGS,
-dnl and LIBARCHIVE_CPPFLAGS to appropriate values for the identified instance of
-dnl libarchive. The values are AC_SUBST'd, so a user could, for example, simply
-dnl include @LIBARCHIVE_CPPFLAGS@ in the definition of AM_CPPFLAGS in a Makefile.am.
-dnl
-dnl ENABLED-DEFAULT is either "yes" or "no" and determines whether the default value
-dnl is --with-libarchive or --without-libarchive. It is not possible to specify a
-dnl default directory. More simply, any reasonable choice for a default should just
-dnl go into the auto-detect list.
-dnl
-dnl The macro defines the symbol HAVE_LIBARCHIVE if the library is found. You
-dnl should use autoheader to include a definition for this symbol in a config.h
-dnl file. Sample usage in a C/C++ source is as follows:
-dnl
-dnl #ifdef HAVE_LIBARCHIVE
-dnl #include <archive.h>
-dnl #endif /* HAVE_LIBARCHIVE */
