On the page http://boost.org/libs/filesystem/doc/operations.htm, in the "rename" section: "Note: Some operating systems with multiple roots<http://boost.org/libs/filesystem/doc/index.htm#multi-root_filesystem>do not allow *rename* operations between roots, and such an attempted *rename* with throw a * filesystem_error <http://boost.org/libs/filesystem/doc/exception.htm>*exception.." Should read: * *"Note: Some operating systems with multiple roots<http://boost.org/libs/filesystem/doc/index.htm#multi-root_filesystem>do not allow *rename* operations between roots, and such an attempted *rename* will throw a * filesystem_error <http://boost.org/libs/filesystem/doc/exception.htm>*exception." E.g. change "with" to "will". Note also that there is an extra period at the end of the sentence. -- Caleb Epstein caleb dot epstein at gmail dot com
