Nick Craig-Wood 7060777d1d docs: fix hugo warning: found no layout file for "html" for kind "term"
Hugo has been making this warning for a while

WARN found no layout file for "html" for kind "term": You should
create a template file which matches Hugo Layouts Lookup Rules for
this combination.

This turned out to be the addition of the `groups:` keyword to the
command frontmatter. Hugo is doing something with this keyword though
this isn't documented in the frontmatter documentation.

The fix was removing the `groups:` keyword from the frontmatter since
it was never used by hugo.

# rclone copyto
Copy files from source to dest, skipping identical files.
## Synopsis
If source:path is a file or directory then it copies it to a file or
directory named dest:path.
This can be used to upload single files to other than their current
name. If the source is a directory then it acts exactly like the
[copy](/commands/rclone_copy/) command.
So
rclone copyto src dst
where src and dst are rclone paths, either remote:path or
/path/to/local or C:\windows\path\if\on\windows.
This will:
if src is file
copy it to dst, overwriting an existing file if it exists
if src is directory
copy it to dst, overwriting existing files if they exist
see copy command for full details
This doesn't transfer files that are identical on src and dst, testing
by size and modification time or MD5SUM. It doesn't delete files from
the destination.
**Note**: Use the `-P`/`--progress` flag to view real-time transfer statistics
```
rclone copyto source:path dest:path [flags]
```
## Options
```
-h, --help help for copyto
```
## Copy Options
Flags for anything which can Copy a file.
```
--check-first Do all the checks before starting transfers
-c, --checksum Check for changes with size & checksum (if available, or fallback to size only).
--compare-dest stringArray Include additional comma separated server-side paths during comparison
--copy-dest stringArray Implies --compare-dest but also copies files from paths into destination
--cutoff-mode HARD|SOFT|CAUTIOUS Mode to stop transfers when reaching the max transfer limit HARD|SOFT|CAUTIOUS (default HARD)
--ignore-case-sync Ignore case when synchronizing
--ignore-checksum Skip post copy check of checksums
--ignore-existing Skip all files that exist on destination
--ignore-size Ignore size when skipping use modtime or checksum
-I, --ignore-times Don't skip items that match size and time - transfer all unconditionally
--immutable Do not modify files, fail if existing files have been modified
--inplace Download directly to destination file instead of atomic download to temp/rename
--max-backlog int Maximum number of objects in sync or check backlog (default 10000)
--max-duration Duration Maximum duration rclone will transfer data for (default 0s)
--max-transfer SizeSuffix Maximum size of data to transfer (default off)
-M, --metadata If set, preserve metadata when copying objects
--modify-window Duration Max time diff to be considered the same (default 1ns)
--multi-thread-chunk-size SizeSuffix Chunk size for multi-thread downloads / uploads, if not set by filesystem (default 64Mi)
--multi-thread-cutoff SizeSuffix Use multi-thread downloads for files above this size (default 256Mi)
--multi-thread-streams int Number of streams to use for multi-thread downloads (default 4)
--multi-thread-write-buffer-size SizeSuffix In memory buffer size for writing when in multi-thread mode (default 128Ki)
--no-check-dest Don't check the destination, copy regardless
--no-traverse Don't traverse destination file system on copy
--no-update-dir-modtime Don't update directory modification times
--no-update-modtime Don't update destination modtime if files identical
--order-by string Instructions on how to order the transfers, e.g. 'size,descending'
--partial-suffix string Add partial-suffix to temporary file name when --inplace is not used (default ".partial")
--refresh-times Refresh the modtime of remote files
--server-side-across-configs Allow server-side operations (e.g. copy) to work across different configs
--size-only Skip based on size only, not modtime or checksum
--streaming-upload-cutoff SizeSuffix Cutoff for switching to chunked upload if file size is unknown, upload starts after reaching cutoff or when file ends (default 100Ki)
-u, --update Skip files that are newer on the destination
```
## Important Options
Important flags useful for most commands.
```
-n, --dry-run Do a trial run with no permanent changes
-i, --interactive Enable interactive mode
-v, --verbose count Print lots more stuff (repeat for more)
```

```
## Listing Options
Flags for listing directories.
```
--default-time Time Time to show if modtime is unknown for files and directories (default 2000-01-01T00:00:00Z)

```
