Improved binary diff from Christopher Li

This is more intelligent/efficient by combining neighboring inserts,
replaces and deletes. Passes test of converting kernel repo, but
doesn't appear to substantially affect compression or performance.

.SH NAME
hg \- command line interface to the Mercurial source code management system
.SH "SYNOPSIS"


hg [\-v \-d \-q \-y] <command> [command options] [files]

.SH "DESCRIPTION"


The hg(1) command provides a command line interface to the Mercurial system\&.

.SH "NOTE"


Many of the hg commands are not yet subdirectory and/or working directory aware\&. This means that some commands will only work in the top level repository directory or will only accept paths and filenames relative to the top level\&. Merges and commits, in particular, should be done in the top\-level directory\&.

.SH "OPTIONS"

.TP
--debug, \-d
enable debugging output

.TP
--quiet, \-q
suppress output

.TP
--verbose, \-v
enable additional output

.TP
--noninteractive, \-y
do not prompt, assume yes for any required answers

.SH "COMMAND ELEMENTS"

.TP
files ...
indicates one or more filename or relative path filenames

.TP
path
indicates a path on the local machine

.TP
revision
indicates a changeset which can be specified as a changeset id (int), a tag, or a unique substring of the changeset hash value

.TP
repository path
is either the pathname of a local repository of the URI of a remote repository\&. There are two available URI protocols, http:// which is fast and the old\-http:// protocol which is much slower but does not require python on the web host\&.

.SH "COMMANDS"

.TP
add [files ...]
add the given files to the repository\&. Note that this just schedules the files for addition at the next hg commit time\&.

.TP
addremove
add all new files and remove all missing files from the repository\&. new files are ignored if they match any of the patterns in \&.hgignore

.TP
annotate [\-r revision \-u \-n \-c] [files ...]
list the files with each line showing the revision id responsible for that line\&. \-u will add the author to the revision id, \-c will print the changeset hash, and \-n will ...

.TP
branch <path>
create a new branch of the repository indicated by path in the current directory\&. Note that there should not be a repository already initialized in the current directory

.TP
checkout [revision]
check out the indicated version of the repository into the working directory\&. Note that currently no merge occurs with changed files in the working dir\&.

.TP
commit
commit all changed files in the working dir to the repository\&. This uses the EDITOR environment variable to bring up an editor to add a commit comment\&.

.TP
diff [\-r revision] [\-r revision] [files ...]
generate a unified diff of the indicated files\&. If there are no revisions specified, the working directory file is compared to the tip, one revision specified indicates a comparison between the working directory file and the specified revision, two revisions compares the two versions specified\&.

.TP
dump <file> [revision]
print the indicated revision of the file

.TP
dumpmanifest [revision]
print the indicated revision of the manifest (list of version controlled files)

.TP
history
print the revision history of the repository

.TP
init
initialize a repository in the current directory

.TP
log <file>
print the revision history of the specified file

.TP
merge <repository path>
pull any changes from the specified repository to the repository in the current directory\&. Use the value of the HGMERGE environment variable as a program to resolve any merge conflicts between the two repositories\&. An implicit commit is done at the end of this process if there were any merge conflicts\&. Note that merge does not yet merge with changed files in the working dir\&.

.TP
remove [files ...]
schedule the indicated files for removal from the repository at the next commit

.TP
serve [\-a addr \-n name \-p port \-t templatedir]
this will start an http server, by default on port 8000, that will allow browsing the repository using the hgweb interface and will allow merging from the repository\&. \-a sets the interface address, \-p the port to listen on, \-n the name of the repository and \-t sets the location of the template directory\&.

.TP
status
list new, changed, and missing files in the working directory

.TP
tags
list the current tags

.SH "ENVIRONMENT VARIABLES"

.TP
HGMERGE
points to an executable to use for resolving merge conflicts, the program will be executed with four arguments: local file, remote file, ancestor file, and original filename\&.

.TP
HGUSER
this is the string used for the author value of a commit

.TP
HG_OPTS
this string is used for default arguments to hg

.TP
PYTHONPATH
this is used by Python to find imported modules and needs to be set appropriately based on where mercurial is installed

.TP
EMAIL
if HGUSER is not set, this will be used next as the author value for a commit

.TP
LOGNAME
if neither HGUSER nor EMAIL is set, LOGNAME will be used (with @hostname appended) as the author value for a commit

.TP
EDITOR
this is the name of the editor to use when committing

.SH "FILES"

.TP
\&.hgignore
this file contains regular expressions (one per line) that describe file names that should be ignored by hg

.TP
\&.hgtags
this file contains changeset hash values and text tag names (one of each seperated by spaces) that correspond to tagged versions of the repository contents\&.

.TP
$HOME/\&.hgpaths
this file contains a mapping from a symbolic name to a repository path (which could be a local path or a remote URI), the format is <symbolic name> <repository path> with each mapping on a seperate line

.SH "BUGS"


Probably lots, please post them to the mailing list (See Resources below) when you find them\&.
