Say you want to fetch Twitter profiles for a list of accounts that are stored in another database:

$ twitter-to-sqlite users-lookup users.db --attach attending.db \
    --sql "select Twitter from attending.attendes where Twitter is not null"

The SQL query you feed in is expected to return a list of screen names suitable for processing further by the command.

Should be supported by all three of:

• twitter-to-sqlite users-lookup
• twitter-to-sqlite user-timeline
• twitter-to-sqlite followers and friends

The --attach option allows other SQLite databases to be attached to the connection. Without it the SQL query will have to read from the single attached database.
