=========
Name
----
pactree - package dependency tree viewer
Synopsis
--------
'pactree' [options] package
Description
-----------
Pactree produces a dependency tree for a package.
By default, a tree-like output is generated, but with the '\--graph' option, a Graphviz
description is generated.
Options
-------
*-a, \--ascii*::
Use ASCII characters for tree formatting. By default, pactree will use Unicode
line drawing characters if it is able to detect that the locale supports them.
*-b, \--dbpath*::
Specify an alternative database location.
*-c, \--color*::
Colorize output.
*-d, \--depth <num>*::
Limits the number of levels of dependency to show. A zero means
show the named package only, one shows the packages that are directly
required.
*-g, \--graph*::
Generate a Graphviz description. If this option is given, the '\--color' and
'\--linear' options are ignored.
*-h, \--help*::
Output syntax and command-line options.
*-l, \--linear*::
Prints package names at the start of each line, one per line.
*-r, \--reverse*::
Show packages that depend on the named package.
*-s, \--sync*::
Read package data from sync databases instead of local database.
*-u, \--unique*::
List dependent packages once. Implies '\--linear'.
*\--config <file>*::
Specify an alternate pacman configuration file.
