"Revision control, also known as version control and source control ... is the
management of changes to documents, computer programs, large web sites, and
other collections of information". That what wikipedia says about VCS, also in
the overview they define a VCS as "... any kind of practice that tracks and
provides control over changes to source code."

Today, you can find many great, good, bad and ugly version control systems
like Git, Mercurial, Bazzar, SVN, CVS [order is not arbitrary]... but It turns
out none of them is good enough for te company, a company that a friend of
mine has interned at and told me about their ultimate VCS.

In this company - a well known multinational company that I'm not going to
name -, if you want to proceed with a change you don't need to fork or clone
or pull. What you do is that you duplicte the lines that you are willing to
change, then comment the old ones and put a comment before and after the new
code where you put an ID. To get this ID you insert a record in a Microsoft
Access database where you specify changes and reasons etc, then you get the ID
of that record and put it back in the comment. Changes are copied manually and
added to the master if they are correct and god knows what test system they
have.

Wow, amazing !! I couldn't believe this reactionary VCS, and what are the
reasons behind this choice. And yes I called it a VCS because it's a
"...practice that tracks and provides control over changes to source code"
