How to squash all migrations into a single one and clear logs to have only one record

[xperiandri]

I have to many migration files so I want to squash them per folder I use. And from that point work as if I have a database where only version 1 migrations exist and only version 1 migrations vere applied.
Squashing itself is pretty simple. Either manually or by dumping a DB.
But how to clean the log record table? Will calling Repair() help with that?
