| .SH DESCRIPTION |
| The master source tree for Plan 9 from User Space is maintained |
| using the source control system Mercurial |
| as a substitute for Plan 9's |
| \fIreplica\fR(8) and dump file system. |
| .PP |
| The first argument to |
| .I hg |
| is a command, which determines the form of the rest of the command line. |
| .PP |
| The |
| .B clone |
| command downloads a copy of the tree into the directory |
| .BR plan9 , |
| which it will create. |
| After |
| .B hg |
| .BR clone , |
| the other commands listed |
| should be run within the |
| .B plan9 |
| directory tree. |
| .PP |
| Unlike CVS, Mercurial downloads the entire revision history |
| of Plan 9 from User Space |
| in addition to the current tree. |
| .PP |
| .I Hg |
| .I pull |
| incorporates changes from the master repository |
| into the local revision history. |
| The |
| .B -u |
| flag applies these changes to the current file tree. |
| .PP |
| .I Hg |
| .I diff |
| runs Unix's |
| .IR diff (1) |
| to compare the files in the local tree with the corresponding |
| files in the revision history. |
| By default it compares against the version that was most recently |
| incorporated into the local tree. |
| The |
| .B -r |
| flag specifies an alternate version to compare against. |
| The special revision |
| .B tip |
| refers to the most recent version on the server. |
| .PP |
| .I Hg |
| .I serve |
| starts an HTTP server serving information about |
| the local repository at the address |
| .BR http://localhost:8000/ . |
| .PP |
| .I Hg |
| .I view |
| starts an interactive history viewer. |
| .PP |
| The Mercurial tree can be inspected on the web at |
