. . ATE (document name) [userid] This action creates a new document with the specified name, which is created by the specified user Example: CREATE Object_Oriented_Programming ali Outcomes: CONFIRMED, DUPLICATE, NOT FOUND A document is a duplicate if has already been created. Duplicates are ignored after being reported. The name of a document is a sequence of at most 80 non-whitespace characters. The command reports not found if the user does not exist in the system. No further processing is done in this case. The created document is initially empty. APREND Documents Your wiki should consist of a set of documents. Each document has a title (which is unique among all documents in the wiki) and contents. Each document is a sequence of lines of plain text. When a document is created, it is initially empty. Users can update the documents in limited ways: they can replace or delete a line (which already exists in the document) or they can add a new line to the end of the document. Each time a document is updated, the change that is made is saved. At any time, the user can ask to see both the most current version of any document and the history of all changes made to a document
