Commit - In the document control, "commit" is referred to the process of putting the document that was taken out from the repository back to the repository after making the desired changes. Commit, along with check-out and check-in, forms one of the basic commands of the Subversion Methodology. Normally - when you perform the operation of putting back your changes to the repository, there will be a dialogue box which will ask for comments from the user where he can specify the reasons of the changes being made.
