To check the project in, complete the following steps:
In the Project Editor
In the Project Tree, checkmark all projects by right-clicking anywhere in the Project Tree,
and then choosing Context menu > Select From All Projects.
You now see all the files in all the projects.
Press the Filters... button.
The Filters... dialog appears.
In the File Types tab, clear the Make check box to filter out SNiFF+'s Makefiles from the
Project Editor's File List (we assume you are using SNiFF+'s Make Support).
SNiFF+'s Make Support files are generated and maintained by SNiFF+, so there's no
reason to version control them.
Press the OK button to apply changes and to close the Filters... dialog.
Choose File > Select All.
Choose File > Check In....

SNiFF+ informs you that it cannot find
the directories of the shared project in
the RWE root directory (they haven't
been created yet). You will now have
SNiFF+ initialize your RWE by copying
the SSWE project directory structure into
the RWE.
This dialog will reappear for each new
Repository directory, unless you select
the Repeat check box.
Select the Repeat checkbox and press Yes to create the necessary Repository directories
for the project.
When SNiFF+ has finished initializing your RWE, the Check In dialog appears.
In the Check In dialog
You can use this dialog to check in versions of single or multiple files.When you have made changes to multiple files, you can check in all the files at the same time and associate them with a change set. By doing so, you can perform a variety of version-control operations on all the files in a change set at the same time.
At this point, although we haven't made any changes, we will make use of the Change Set field to indicate that we are checking in the initial versions of all the files in the project.
Leave the Version field blank. SNiFF+ will automatically assign a version number (1.1)
and later increment it automatically.
In the Change Set field, enter a name for the change set, e.g.,
