Long: strings.ReplaceAll(`Checks that hashsums of destination files match the SUM file.

It compares hashes (MD5, SHA1, etc) and logs a report of files which
|
|
don't match. It doesn't alter the file system.
|
|
|
|
The sumfile is treated as the source and the dst:path is treated as
|
|
the destination for the purposes of the output.

|
|
|
If you supply the |--download| flag, it will download the data from the remote
|
|
and calculate the content hash on the fly. This can be useful for remotes
|
|
that don't support hashes or if you really want to check all the data.
|
|
|
|
Note that hash values in the SUM file are treated as case insensitive.
