I don't know whether this is a bug in documentation or code, in documentation for symbol indexes [[ https://secure.phabricator.com/book/phabricator/article/diffusion_symbols/| Diffusion User Guide: Symbol Indexes]] there is an example at the end of document.
> $ ./scripts/symbols/import_repository_symbols.php **r**REPO < symbols_data
if I include the **r** before callsign like this example, I will get the following error:
> Repository 'rTXE' does not exist
but without the **r** it works fine
