load()

static bool ThePEG::DynamicLoader::load ( string  file )

static

Try to load the file given as argument.

If the filename does not begin with a '/', try to prepend the paths one at the time until success. If all fail try without prepending a path.

Returns

true if the loading succeeded, false otherwise.
