+.SH NAME
+pacman \- package manager utility
+.SH SYNOPSIS
+\fBpacman  <operation> [options] <package> [package] ...\fP
+.SH DESCRIPTION
+\fBpacman\fP is a \fIpackage management\fP utility that tracks installed
+packages on a linux system.  It has simple dependency support and the ability
+to connect to a remote ftp server and automatically upgrade packages on
+the local system.  pacman package are \fIgzipped tar\fP format.
+.SH OPERATIONS
+.TP
+.B "\-A, \-\-add"
+Add a package to the system.  Package will be uncompressed
+into the installation root and the database will be updated.
+.TP
+.B "\-R, \-\-remove"
+Remove a package from the system.  Files belonging to the
+specified package will be deleted, and the database will
+be updated.  Most configuration files will be saved with a
+\fI.pacsave\fP extension unless the \fB--nosave\fP option was
+used.
+.TP
+.B "\-U, \-\-upgrade"
+Upgrade a package.  This is essentially a "remove-then-add"
+process.  See \fBHANDLING CONFIG FILES\fP for an explanation
+on how pacman takes care of config files.
+.TP
+.B "\-Q, \-\-query"
+Query the package database.  This operation allows you to
+view installed packages and their files, as well as meta-info
+about individual packages (dependencies, conflicts, install date,
+build date, size).  This can be run against the local package
+database or can be used on individual .tar.gz packages.  See
+\fBQUERY OPTIONS\fP below.
+.TP
+.B "\-S, \-\-sync"
+Synchronize packages.  With this function you can install packages
+directly from the ftp servers, complete with all dependencies required
+to run the packages.  For example, \fBpacman -S qt\fP will download
+qt and all the packages it depends on and install them. You could also use
+\fBpacman -Su\fP to upgrade all packages that are out of date (see below).
+.TP
+.B "\-V, \-\-version"
+Display version and exit.
+.TP
+.B "\-h, \-\-help"
+Display syntax for the given operation.  If no operation was
+supplied then the general syntax is shown.
+.SH OPTIONS
+.TP
+.B "\-v, \-\-verbose"
+Output more status and error messages.
+.TP
+.B "\-f, \-\-force"
+Bypass file conflict checks,, overwriting conflicting files.  If the
+package that is about to be installed contains files that are already
+installed, this option will cause all those files to be overwritten.
+This option should be used with care, ideally not at all.
+.TP
+.B "\-d, \-\-nodeps"
+Skips all dependency checks.  Normally, pacman will always check
+a package's dependency fields to ensure that all dependencies are
+installed and there are no package conflicts in the system.  This
+switch disables these checks.
+.TP
+.B "\-n, \-\-nosave"
+(only used with \fB--remove\fP)
+Instructs pacman to ignore file backup designations.  Normally, when
+a file is about to be \fIremoved\fP from the system the database is first
+checked to see if the file should be renamed to a .pacsave extension.  If
+\fB--nosave\fP is used, these designations are ignored and the files are
+removed.
+.TP
+.B "\-r, \-\-root <path>"
+Specify alternative installation root (default is "/"). This
+should \fInot\fP be used as a way to install software into
+e.g. /usr/local instead of /usr. Instead this should be used
+if you want to install a package on a temporary mounted partition,
+which is "owned" by another system. By using this option you not only
+specify where the software should be installed, but you also
+specify which package database to use.
+.SH SYNC OPTIONS
+.TP
+.B "\-y, \-\-refresh"
+Download a fresh copy of the master package list from the ftp server
+defined in \fI/etc/pacman.conf\fP.  This should typically be used each
+time you use \fB--sysupgrade\fP.
+.TP
+.B "\-u, \-\-sysupgrade"
+Upgrades all packages that are out of date.  pacman will examine every
+package installed on the system, and if a newer package exists on the
+server it will upgrade.  pacman will present a report of all packages
+it wants to upgrade and will not proceed without user confirmation.
+Dependencies are automatically resolved at this level and will be
+installed/upgraded if necessary.
+.TP
+.B "\-s, \-\-search <string>"
+This will search each package in the package list for names or descriptions
+that contains <string>.
+.TP
+.B "\-c, \-\-clean"
+Remove packages from the cache.  When pacman downloads packages,
+it saves them in \fI/var/cache/pacman/pkg\fP.  If you need to free up
+diskspace, you can remove these packages by using the --clean option.
+.SH QUERY OPTIONS
+.TP
+.B "\-o, \-\-owns <file>"
+Search for the package that owns <file>.
+.TP
+.B "\-l, \-\-list"
+List all files owned by <package>.  Multiple packages can be specified on
+the command line.
+.TP
+.B "\-i, \-\-info"
+Display information on a given package.  If it is used with the \fB-p\fP
+option then the .PKGINFO file will be printed.
+.TP
+.B "\-p, \-\-file"
+Tells pacman that the package supplied on the command line is a
+file, not an entry in the database.  Pacman will decompress the
+file and query it.  This is useful with \fB--info\fP and \fB--list\fP.
+.SH HANDLING CONFIG FILES
+pacman uses the same logic as rpm to determine action against files
+that are designated to be backed up.  During an upgrade, it uses 3
+md5 hashes for each backup file to determine the required action:
+one for the original file installed, one for the new file that's about
+to be installed, and one for the actual file existing on the filesystem.
+After comparing these 3 hashes, the follow scenarios can result:
+.TP
+original=\fBX\fP, current=\fBX\fP, new=\fBX\fP
+All three files are the same, so we win either way.  Install the new file.
+.TP
+original=\fBX\fP, current=\fBX\fP, new=\fBY\fP
+The current file is un-altered from the original but the new one is
+different.  Since the user did not ever modify the file, and the new
+one may contain improvements/bugfixes, we install the new file.
+.TP
+original=\fBX\fP, current=\fBY\fP, new=\fBX\fP
+Both package versions contain the exact same file, but the one
+on the filesystem has been modified since.  In this case, we leave
+the current file in place.
+.TP
+original=\fBX\fP, current=\fBY\fP, new=\fBY\fP
+The new one is identical to the current one.  Win win.  Install the new file.
+.TP
+original=\fBX\fP, current=\fBY\fP, new=\fBZ\fP
+All three files are different.  So we install the new file, but back up the
+old one to a .pacsave extension.  This way the user can move the old configuration
+file back into place if he wishes.
+.SH CONFIGURATION
+pacman will attempt to read \fI/etc/pacman.conf\fP each time it is invoked.  Currently
+the only options in it are for the --sync operation, but more may be added later.
+.TP
+.B "Sync_Tree_Name"
+Sets the name of the package set you wish to follow.  The common choices are \fIcurrent\fP
+and \fIstable\fP.  You could also specify a specific package version, eg, 0.3.
+.TP
+.B "Sync_Server"
+This is the hostname of the ftp server that will be used for downloading lists and
+packages. eg, \fIftp.ibiblio.org\fP.
+.TP
+.B "Sync_Tree_Path"
+This is the full path name (on the ftp server) to the package tree you are following.
+So if you are following \fIcurrent\fP, on \fIftp.ibiblio.org\fP, you would use
+\fI/pub/linux/distributions/archlinux/current\fP.

-.SH NAME
-pacman \- package manager utility
-.SH SYNOPSIS
-\fBpacman  <operation> [options] <package> [package] ...\fP
-.SH DESCRIPTION
-\fBpacman\fP is a \fIpackage management\fP utility.  Package
-information is maintained in a basic text format for easy
-tweaking, if necessary, and packages are in a standard
-\fIgzipped tar\fP format.
-.SH OPERATIONS
-.TP
-.B "\-A, \-\-add"
-Add a package to the system.  Package will be uncompressed
-into the installation root and the database will be updated.
-.TP
-.B "\-R, \-\-remove"
-Remove a package from the system.  Files belonging to the
-specified package will be deleted, and the database will
-be updated.  Note that most configuration files will be
-be renamed with \fI.pacsave\fP extensions.
-.TP
-.B "\-U, \-\-upgrade"
-Upgrade a package.  This is essentially a "remove-then-install"
-process.  Most configuration files will be not be overwritten.
-.TP
-.B "\-Q, \-\-query"
-Query the package database.  This operation allows you to
-view installed packages and their files.  See \fBQUERY OPTIONS\fP
-below.
-.TP
-.B "\-V, \-\-version"
-Display version and exit.
-.TP
-.B "\-h, \-\-help"
-Display syntax for the given operation.  If no operation was
-supplied, then the general syntax is shown.
-.SH QUERY OPTIONS
-.TP
-.B "\-o, \-\-owns <file>"
-Output the name of the package that owns <file>.
-.TP
-.B "\-l, \-\-list"
-Instead of outputting the package name, output the list of
-files owned by the package.
-.TP
-.B "\-i, \-\-info"
-Output the .PKGINFO file contained in <package>.  This option
-can only be used with the \fB-p\fP option.
-.TP
-.B "\-p, \-\-file"
-Tells pacman that the package supplied on the command line is a
-file, not an entry in the database.  Pacman will decompress the
-file and query it.  This is useful with \fB--info\fP and \fB--list\fP.
-.SH OPTIONS
-.TP
-.B "\-v, \-\-verbose"
-Output more status and error messages.
-.TP
-.B "\-f, \-\-force"
-Force installation, overwriting conflicting files.  If the package
-that is about to be installed contains files that are already
-installed this option will cause all those files to be overwritten.
-This option should be used with care, preferably not at all.
-.TP
-.B "\-n, \-\-nosave"
-Instructs pacman to ignore file backup designations.  Normally, when
-a file is about to be \fIremoved\fP from the system the database is first
-checked to see if the file should be renamed to a .pacsave extension
-(indicated by a '\fB*\fP' prefix in the pacman database).  The \fB--nosave\fP
-will turn off these file backups.  Normally, when a file is about to be \fIadded\fP
-or \fIupgraded\fP and a starred file already exists, pacman will write
-the new file to a .pacnew extension and keep the old one in place.  In this
-case, \fB--nosave\fP instructs pacman to overwrite the existing file.
-.TP
-.B "\-r, \-\-root <path>"
-Specify alternative installation root (default is "/"). This
-should \fInot\fP be used as a way to install software into
-e.g. /usr/local instead of /usr. Instead this should be used
-if you want to install a package on a temporary mounted partition,
-which is "owned" by another system. By using this option you not only
-specify where the software should be installed, but you also
-specify which package database to use.

-.SH NAME
-pacsync \- package update frontend for pacman
-.SH SYNOPSIS
-\fBpacsync  [--root <root>] <operation> [package] [package] ...\fP
-.SH DESCRIPTION
-\fBpacsync\fP is a \fIpackage update\fP frontend for the
-\fIpacman\fP package manager.  It keeps track of the versions
-of packages installed on the local system and the versions of
-packages on a remote server.  This allows you to issue a single
-command and have you system's packages brought into sync.
-.SH OPERATIONS
-.TP
-.B "sync"
-Download a new copy of the package list from the server.  This
-should be done regularly, usually before an "install", "upgrade"
-or "sysupgrade" command.
-.TP
-.B "install <package>"
-Install a new package. \fBpacsync\fP will first look for the package
-in the cache directory.  If it is not there, it will attempt to
-download the file from the server.  On success, the package will
-be installed.  (Note that the downloaded file is also copied to
-a cache directory on your filesystem.  You can delete it with
-"clean").
-.TP
-.B "upgrade <package>"
-Upgrade a package.  This is the same as \fIinstall\fP, except a package
-is upgraded (ie, it is already installed in the system).
-.TP
-.B "report"
-Generate an upgrade report.  This operation will compare all local
-package versions to remote versions, and then show you a report of
-the differences.
-.TP
-.B "sysupgrade"
-Full system upgrade.  This is the same as report except after confirmation,
-\fBpacsync\fP will upgrade all packages that are not up to date.
-.TP
-.B "clean"
-This will remove all downloaded packages from the cache directory.  This
-can/should be used regularly to free up diskspace.
-.SH CONFIGURATION
-Configuration options are stored in /etc/pacsync.conf.  Currently there is only
-one directive.
-.TP
-.B "SYNC_SERVER"
-This should be set to the full URL of the download server closest to you.
-FTP is preferred, but HTTP is supported also, provided you have wget.

-#
-# /etc/pacsync.conf
-#
-#
-# From here you can configure pacsync to follow a certain package tree.
-# Typically this is either 'stable' or 'current', but you can pick
-# specific versions as well (eg, '0.2').  Read below for the structure.
-#
-
-# Arch Linux servers follow this directory structure:
-#
-# 0.1
-#  |- iso
-#  |   |- i686
-#  |- os
-#  |   |- i686
-# 0.2
-#  |- iso
-#  |   |- i686
-#  |- os
-#  |   |- i686
-# 0.3
-#  |- iso
-#  |   |- i686
-#  |- os
-#  |   |- i686
-# current -> 0.3/os/i686
-# stable  -> 0.2/os/i686
-#
-#
-# Set your SYNC_SERVER according to the version you wish to follow.  For
-# example, if you simply wish to follow the stable branch (whatever version
-# it may be), then you can set SYNC_SERVER as follows:
-#
-#   SYNC_SERVER="ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/stable"
-#
-# Other examples:
-#   SYNC_SERVER="ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/0.2/os/i686"
-#   SYNC_SERVER="ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/0.3/os/i686"
-#   SYNC_SERVER="ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/current"
-#
-
-
-#
-# SYNC_SERVER: the full location of the package repository (ftp or http)
-#
-SYNC_SERVER="ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/current"
-
-
-#
-# OTHER LOCATIONS (MIRRORS)
-#
-#   Note: ibiblio.org will typically be fastest.  Please stick with them unless
-#         you've got a good reason to change.
