[Python-Dev] Joel Spolsky on Mercurial

[Terry Reedy]

In what might be his last Joel on Software post (for awhile, at least)
http://www.joelonsoftware.com/items/2010/03/17.html

Summary:
Early 2009: Joel disses DVCSes. His programmers switch from subversion 
to hg. Joel grumbles. His programmers develop an hg-related product. 
Joel takes a better look.

Joel sees the light: Subversion controls versions, hg controls changes; 
this make merging much easier.
Joel flips (his opinion): Switch now!

Joel write hg tutorial: http://hginit.com/
It starts with "Subversion Re-education" for existing version-oriented 
system users and continue with "Ground up Mercurial" where new vcs users 
can start. It has several simple examples.

Having gotten that far, I think this might be worth referencing in new 
dev docs.
