+# Default revdep-rebuild configuration file

+# revdep-rebuild no longer uses hardcoded paths. To change the default 
+# behavior the following variables can be changed:
+#
+# LD_LIBRARY_MASK - Mask of specially evaluated libraries
+#
+# SEARCH_DIRS - List of directories to search for executables and libraries
+#	Use this for directories that are not included in PATH or ld.so.conf.
+#	An application should normally not have to set this variable
+#
+# SEARCH_DIRS_MASK - List of directories to not search
+#	Use this for directories that should not be searched by revdep-rebuild
+#	This is normally used by binary packages such as openoffice-bin
+#
+# Note: This file is sourced using bash by the revdep-rebuild script

+# revdep-rebuild: Reverse dependency rebuilder.
+# Original Author: Stanislav Brabec
+# Current Maintainer: Paul Varner <fuzzyray@gentoo.org>
+
+# Known problems:
+#
+# In exact ebuild mode revdep-rebuild can fail to properly order packages,
+# which are not up to date.
+# http://bugs.gentoo.org/show_bug.cgi?id=23018
+#
+# Rebuilding using --package-names mode should be default, but emerge has no
+# feature to update to latest version of defined SLOT.
+# http://bugs.gentoo.org/show_bug.cgi?id=4698
+
+# Customizable variables:
+#
+# LD_LIBRARY_MASK - Mask of specially evaluated libraries
+# SEARCH_DIRS - List of directories to search for executables and libraries
+# SEARCH_DIRS_MASK - List of directories to not search
+#
+# These variables can be prepended to either by setting the variable in 
+# your environment prior to execution, or by placing an entry in
+# /etc/make.conf.
+#
+# An entry of "-*" means to clear the variable from that point forward.
+# Example: env SEARCH_DIRS="/usr/bin -*" revdep-rebuild will set SEARCH_DIRS
+# to contain only /usr/bin

+.SH "NAME"
+revdep\-rebuild \- Gentoo: Reverse Dependency Rebuilder
+.SH "SYNOPSIS"
+.B revdep\-rebuild
+[OPTIONS] [\-\-] [EMERGE OPTIONS]
+.SH "DESCRIPTION"
+revdep\-rebuild scans libraries and binaries for missing shared library dependencies and attempts to fix them by re\-emerging those broken binaries and shared libraries.  It is useful when an upgraded package breaks other software packages that are dependent upon the upgraded package.
+.SH "OPTIONS"
+.TP 
+.B \-C | \-\-nocolor
+Turn off colored output. (This option is also passed to portage.)
+.TP      
+.B \-e | \-\-exact
+Emerge the most recent version of found packages, without regard to SLOT.
+.TP 
+.B \-h | \-\-help
+Print usage.
+.TP
+.B \-i | \-\-ignore
+Delete temporary files from previous runs.
+.TP
+.B \-k | \-\-keep\-temp
+Force revdep\-rebuild not to delete temporary files after it successfully rebuilds packages. This option will NOT prevent revdep\-rebuild from deleting inconsistent or out\-of\-date temporary files.
+.TP
+.B \-\-library NAME | -L NAME
+Search for reverse dependencies for a particular library or group of libraries, rather than every library on the system. Emerge packages that use the named library. NAME can be a full path to a library or basic regular expression.  (See regex(7).)
+.TP 
+.B \-l | \-\-no\-ld\-path
+Do not set LD_LIBRARY_PATH. \fBNote:\fR Using this option will cause revdep-rebuild to report some false positives.
+.TP 
+.B \-o | \-\-no-order
+Do not check the build order against the deep dependency list.  This will make revdep-rebuild faster, but it can cause emerge failures.  Please try revdep\-rebuild without \-o before reporting any bugs.
+.TP 
+.B \-p | \-\-pretend
+Do a dry-run.  Do not delete temporary files.  (\-k \-p is redundant, but harmless.)  \-\-pretend is assumed when not running revdep\-rebuild as root.
+.TP 
+.B \-P | \-\-no\-progress
+Turn off the progress meter
+.TP 
+.B \-q | \-\-quiet
+Print less output and disable the progress meter.  (This option is also passed to portage.)
+.TP 
+.B \-u UTIL | \-\-no-util UTIL
+Do not use features provided by UTIL.
+UTIL can be one of portage-utils or pkgcore, or it can be a \fBquoted\fR space-delimited list.
+.TP
+.B \-v | \-\-verbose
+More output.  (Prints the revdep\-rebuild search environment.)
+.TP
+.B All other options (including unrecognized ones) are passed to the emerge command.  Single\-letter options may not be combined, so for example, \-pv is not valid.  Please use \-p \-v.
+.SH "CONFIGURATION"
+revdep\-rebuild no longer uses hardcoded paths. To change the default behavior the following variables can be changed by the user.
+
+LD_LIBRARY_MASK \- Mask of specially evaluated libraries
+.LP 
+SEARCH_DIRS \- List of directories to search for executables and libraries
+.LP 
+SEARCH_DIRS_MASK \- List of directories to not search
+
+You can prepend to these variables by setting the variable in your environment prior to execution, by placing an entry in /etc/make.conf, or by placing a file in /etc/revdep\-rebuild containing the appropriate variables.
+
+The variables are read and set in the following order:
+
+environment settings \- one time changes by user
+.br 
+/etc/make.conf \- persistent changes by user
+.br 
+/etc/revdep\-rebuild/* \- persistent changes by ebuild authors
+
+While a user can edit and modify the files in the /etc/revdep\-rebuild directory, please be aware that the /etc/revdep\-rebuild directory is not under configuration protection and files can be removed and/or overwritten by an ebuild. To change this add /etc/revdep\-rebuild to the CONFIG_PROTECT variable in /etc/make.conf.
+
+An entry of "\-*" means to clear the variable from that point forward.
+Example: SEARCH_DIRS="/usr/bin \-*" will set SEARCH_DIRS to contain only /usr/bin
+
+revdep\-rebuild honors the NOCOLOR and PORTAGE_NICENESS variables from /etc/make.conf
