+# poudlist-all.sh
+
+## Description
+A small script to generate a list of all ports installed, excluding leaf ports which you don't want to be rebuilt in conjunction of others.<br>
+The author created this script because `poudriere bulk -a -j jailname` forces rebuilding ALL ports, which any of ports they depends on are updated, regardless it's too time-consuming or not.
+
+## Usage
+No command line arguments.Simply run it as a bourne shell script.<br>
+Once the resulting list is generated (default: /poudriere/pkglist.all), you can run `poudriere bulk -f /poudriere/pkglist.all -j jailname` and rebuild too huge monster leaves once it finishes.
+
+## Configuing the script
+No configuration files are supported.<br>
+You need to edit the script and set variables in it.
+
+### Variables for configuration
+#### BLOCKLISTS
+ports origins you want to block from building.<br>
+Each origins must be the form poudriere can accept.<br>
+Note that poudriere does not block building listed ports if it is depended upon by any non-listed ports.
+
+Beware! If the origin is NOT a leaf ports, you must specify ALL origins of the ports/pkgs which depends on it, for example, japanese/libreoffice as the actual leaf of editors/libreoffice must be specified in conjunction with editors/libreoffice.
+
+#### PORTSDIR
+The directory where ports tree to be used exists.<br>
+Default is where vanilla FreeBSD expects: /usr/ports
+
+#### LISTDIR
+The directory where the list is generated.<br>
+Default is: /poudriere
+
+#### LISTFILE
+The file name of the list to be generated.<br>
+Default is: pkglist.all
+
+#### TMPDIR
+The directory where temporary working file is generated.<br>
+Requires Read/Write permission for the user running this script.
+
+#### TMPFILE
+The file name of the temporary working file to be used.<br>
+Default is the string of LISTFILE appended uid, date and time.<br>
+So would be no need to modify.
