If you want to customize the version string, as reported by
the `rclone version` command, you can set one of the variables `fs.Version`,
`fs.VersionTag` (to keep default suffix but customize the number),
or `fs.VersionSuffix` (to keep default number but customize the suffix).
This can be done from the build command, by adding to the `-ldflags`
argument value as shown below.
```
go build -trimpath -ldflags "-s -X github.com/rclone/rclone/fs.Version=v9.9.9-test" -tags cmount
```
On Windows, the official executables also have the version information,
as well as a file icon, embedded as binary resources. To get that with your
own build you need to run the following command **before** the build command.
It generates a Windows resource system object file, with extension .syso, e.g.
`resource_windows_amd64.syso`, that will be automatically picked up by
future build commands.
```
go run bin/resource_windows.go
```
The above command will generate a resource file containing version information
based on the fs.Version variable in source at the time you run the command,
which means if the value of this variable changes you need to re-run the
command for it to be reflected in the version information. Also, if you
override this version variable in the build command as described above, you
need to do that also when generating the resource file, or else it will still
use the value from the source.
```
go run bin/resource_windows.go -version v9.9.9-test
```
