Nick Craig-Wood bff702a6f1 docs: group the global flags and make them appear on command and flags pages
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.

This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Copy the source to the destination. Does not transfer files that are
identical on source and destination, testing by size and modification
time or MD5SUM. Doesn't delete files from the destination. If you
want to also delete files from destination, to make it match source,
use the [sync](/commands/rclone_sync/) command instead.
Note that it is always the contents of the directory that is synced,
not the directory itself. So when source:path is a directory, it's the
contents of source:path that are copied, not the directory name and
contents.
To copy single files, use the [copyto](/commands/rclone_copyto/)
command instead.
If dest:path doesn't exist, it is created and the source:path contents
go there.
For example
rclone copy source:sourcepath dest:destpath
Let's say there are two files in sourcepath
sourcepath/one.txt
sourcepath/two.txt
This copies them to
destpath/one.txt
destpath/two.txt
Not to
destpath/sourcepath/one.txt
destpath/sourcepath/two.txt
If you are familiar with |rsync|, rclone always works as if you had
written a trailing |/| - meaning "copy the contents of this directory".
This applies to all commands and whether you are talking about the
source or destination.
See the [--no-traverse](/docs/#no-traverse) option for controlling
whether rclone lists the destination directory or not. Supplying this
option when copying a small number of files into a large destination
can speed transfers up greatly.
For example, if you have many files in /path/to/src but only a few of
them change every day, you can copy all the files which have changed
recently very efficiently like this:
rclone copy --max-age 24h --no-traverse /path/to/src remote:
**Note**: Use the |-P|/|--progress| flag to view real-time transfer statistics.
**Note**: Use the |--dry-run| or the |--interactive|/|-i| flag to test without copying anything.
