plain

This is the default Asymptote base file, which defines key parts of the drawing language (such as the picture structure). By default, an implicit private import plain; occurs before translating a file and before the first command given in interactive mode. This also applies when translating files for module definitions (except when translating plain, of course). This means that the types and functions defined in plain are accessible in almost all Asymptote code. Use the -noautoplain command-line option to disable this feature.
