Setting up Mercurial:

 Note: some distributions fails to include bits of distutils by

 First, unpack the source:

 $ tar xvzf mercurial-<ver>.tar.gz

 $ cd mercurial-<ver>

 $ python setup.py install   # change python to python2.3 if 2.2 is default

 $ python2.3 setup.py install --home=~

 $ export PYTHONPATH=${HOME}/lib/python  # add this to your .bashrc

 $ export PATH=${HOME}/bin:$PATH         # 

 $ export HGMERGE=tkmerge                # customize this

 And finally:

 $ hg                                    # test installation, show help

 If you get complaints about missing modules, you probably haven't set

 PYTHONPATH correctly.

Setting up a Mercurial project:

 $ cd linux/

 $ hg init         # creates .hg

 $ hg status       # show changes between repo and working dir

 $ hg diff         # generate a unidiff

 $ hg addremove    # add all unknown files and remove all missing files

 $ hg commit       # commit all changes, edit changelog entry

 $ hg export       # export a changeset as a diff

 Mercurial will look for a file named .hgignore in the root of your

 repository contains a set of regular expressions to ignore in file

 paths.

Mercurial commands:

 $ hg history          # show changesets

 $ hg log Makefile     # show commits per file

 $ hg checkout         # check out the tip revision

 $ hg checkout <id>    # check out a specified changeset

                       # IDs can be tags, revision numbers, or unique

                       # subsets of changeset hash numbers

 $ hg add foo          # add a new file for the next commit

 $ hg remove bar       # mark a file as removed

 $ hg verify           # check repo integrity

 $ hg tags             # show current tags

 $ hg annotate [files] # show changeset numbers for each file line

Branching and merging:

 $ cd ..

 $ mkdir linux-work

 $ cd linux-work

 $ hg branch ../linux        # create a new branch

 $ hg checkout               # populate the working directory

 $ <make changes>

 $ hg commit

 $ cd ../linux

 $ hg merge ../linux-work    # pull changesets from linux-work

Importing patches:

 Fast:

 $ patch < ../p/foo.patch

 $ hg addremove

 $ hg commit

 Faster:

 $ patch < ../p/foo.patch

 $ hg commit `lsdiff -p1 ../p/foo.patch`

 Fastest:

 $ cat ../p/patchlist | xargs hg import -p1 -b ../p 

Network support:

 # pull the self-hosting hg repo

 foo$ hg init

 foo$ hg merge http://selenic.com/hg/

 foo$ hg checkout  # hg co works too

 # export your current repo via HTTP with browsable interface

 foo$ hg serve -n "My repo" -p 80

 # merge changes from a remote machine

 bar$ hg merge http://foo/

 bar$ hg co        # checkout the result

 # Set up a CGI server on your webserver

 foo$ cp hgweb.cgi ~/public_html/hg-linux/index.cgi

 foo$ emacs ~/public_html/hg-linux/index.cgi # adjust the defaults

Symbolic repository names:

 Mercurial uses an optional file called ~/.hgpaths to track repo

 locations symbolically. Simply add a line with the name, a space, and

 a URL:

 foo$ echo "main http://selenic.com/hg/" >> ~/.hgpaths

 foo$ hg merge main

 foo$ hg co
