What do I do with an MD5 checksum?

An MD5 checksum is useful for checking that a download was not corrupted. Most unix systems have a tool called md5 or md5sum which will calculate the MD5 checksum of your downloaded file. This can be compared to the checksum on the website to confirm that the file was retrieved successfully.

MD5 file checksums should be used only for the detection of download truncation or data corruption, and should not be used to detect malicious interference.

How do I use the Subversion links?

Some projects provide a "Subversion" link which when viewed through a browser shows only a plain looking view of the individual files in our source code repository (example:

$ svn ls
$ svn co quest-putty

  • trunk - current development
  • tags - tagged releases
  • branch - transient branches of trunk
  • vendor - tracked vendor sources

$ git clone git://
