184 Use 'tahoe cp' to copy files between a local filesystem and a Tahoe
185 virtual filesystem. Any FROM/TO arguments that begin with an alias
186 indicate Tahoe-side files, and arguments which do not indicate local
187 files. Directories will be copied recursively. New Tahoe-side directories
188 will be created when necessary. Assuming that you have previously set up
189 an alias 'home' with 'tahoe create-alias home', here are some examples:
191 tahoe cp ~/foo.txt home: # creates tahoe-side home:foo.txt
193 tahoe cp ~/foo.txt /tmp/bar.txt home: # copies two files to home:
195 tahoe cp ~/Pictures home:stuff/my-pictures # copies recursively
197 Limitations: symlinks, special files (device nodes, named pipes), and
198 non-ASCII filenames are not handled very well. Arguments should not have
199 trailing slashes. 'tahoe cp' does not behave exactly like /bin/cp .
