Hg Init tutorial by Joel Spolsky

written in Python

works with BitBucket (as equivalent to GitHub for Git)

Jan'2014: used heavily at FaceBook because of scaling issues

Aug'2010: Joe Gregorio offers hg-prompt, because the only annoyance of MercurialQueues is accidentally pulling when you have queued patches applied.

MercurialQueues http://hgbook.red-bean.com/read/managing-change-with-mercurial-queues.html

typical starting-up commands

• hg init
• create/edit .hgignore file http://www.selenic.com/mercurial/hgignore.5.html
  • typical files: *.pyc
  • if recognize something afterwords, use forget/remove

my typical cycle (working alone, not pushing to any repository): {{{ hg status hg add hg commit }}}

To undo last commit - hg revert --all -r {version num to revert to}
