From this article : ESEUTIL /r enn /L[path to log files] /s[path to checkpoint file] /d[path to database file] /i
Example: ESEUTIL /r e01 /Lf:\mdbdata /sc:\exchsrvr\mdbdata /dg:\mdbdata /i
These are all the available switches, so look at the article and use only what you need.
Edit: Actually, the easiest way to accomplish this would be to just mount the database. You can specify the log file location under the Properties of the Recovery Storage Group in Exchange System Manager. Log file path points to logs (obviously), and System path is where the checkpoint file is located (you can just point it to the same place as where your logs are; this is the default location usually)
