"Later in the 1980s, Dick Grune used RCS as a building block for a set of "
"shell scripts he initially called cmt, but then renamed to CVS (Concurrent "
"Versions System).  The big innovation of CVS was that it let developers work "
"simultaneously and somewhat independently in their own personal workspaces.  "
"The personal workspaces prevented developers from stepping on each other's "
"toes all the time, as was common with SCCS and RCS. Each developer had a copy "
"of every project file, and could modify their copies independently.  They had "
"to merge their edits prior to committing changes to the central repository."

"Brian Berliner took Grune's original scripts and rewrote them in C, releasing "
"in 1989 the code that has since developed into the modern version of CVS.  "
"CVS subsequently acquired the ability to operate over a network connection, "
"giving it a client/server architecture.  CVS's architecture is centralised; "
"only the server has a copy of the history of the project. Client workspaces "
"just contain copies of recent versions of the project's files, and a little "
"metadata to tell them where the server is.  CVS has been enormously "
"successful; it is probably the world's most widely used revision control "
"system."

"As the 1990s progressed, awareness grew of a number of problems with CVS.  It "

"renaming files and directories.  Worse, its source code is difficult to read "
