The callback function must take a String and return nothing.

Configuration files

function add_configuration(path::String)

By default, chemfiles reads configuration from any file name .chemfilesrc in the current directory or any parent directory. This function can be used to add data from another configuration file.

This function will fail if there is no file at path, or if the file is incorectly formatted. Data from the new configuration file will overwrite any existing data.
