// Most other tests use "config_for_unittests.h" to make testing easier.
// This brings in some code most users won't use.  This test is meant
// entirely to use ctemplate as users will, just #including the public
// .h files directly.  It does hardly any work, and is mainly intended
// as a compile check for the .h files.  It will not work if you use
// a non-standard name for the package namespace (via
//     ./configure --enable-namespace=foo
// ), though you can fix that by changing the namespace alias below.

// These are all the .h files that we export
#include <ctemplate/per_expand_data.h>
#include <ctemplate/template.h>
#include <ctemplate/template_dictionary.h>
#include <ctemplate/template_dictionary_interface.h>
#include <ctemplate/template_emitter.h>
#include <ctemplate/template_enums.h>
#include <ctemplate/template_modifiers.h>
#include <ctemplate/template_namelist.h>
#include <ctemplate/template_pathops.h>
#include <ctemplate/template_string.h>
#include <stdio.h>
#include <string>

// If you used ./configure --enable-namespace=foo, replace 'ctemplate'
// here with 'foo'.
