Python实现的MAC系统下的剪贴板代码，pythonmac,This is a cl

This is a clipboard manipulation module that demonstrates some simple use ofCarbon API. It can double as a Unix-style command-line tool that prints theclipboard contents to stdout or, if specified, copies its stdin to theclipboard, although pbcopy(1) and pbpaste(1) are better suited for that.

By default, the most reasonable choice of the 'TEXT' flavour is used. Otherflavors for special uses can be specified. If there is no "scrap" of a givenflavor, Mac OS API report this as an error. Normally this is suppressed andtreated as empty clipboard, but user can request the program to complain.

By default, the line endings are translated from '\r' (Mac) to '\n' (Unix)when printing to stdout.
