I know other version control software exists, but does anyone use it? Why? What are the differences? All I’ve ever actually seen people use is git.
Not to mention, most developers don’t even really care about which SCM they use.
Get them to use CVS for a while. They will care then.
You clearly haven’t used ClearCase. That would seriously reallign your definition of “pain”… :-)
I used ClearCase too :) And it was painful. But I don’t think CVS and/or ClearCase are considered to be meaningful alternatives to Git at this day and age. I was mostly thinking about Mercurial and Fossil. They are brought up as alternatives to Git more often. That’s my observation at least.
