pnd_make.sh - A script to package "something" into a PND.
Usage:
$(basename ${0}) {--directory|-d} <folder> {--pndname|-p} <file> [{--compress-squashfs|-c}]
[{--genpxml} <file>] [{--icon|-i} <file>] [{--pxml|-x} <file>]
[{--schema|-s} <file>] [{--help|-h}]
Switches:
--compress-squashfs / -c Define whether or not the pnd should be compressed using
squashfs. If this parameter is selected, a compressed pnd
will be created.
--directory / -d Sets the folder that is to be used for the resulting pnd
to <folder>. This option is mandatory for the script to
function correctly.
--genpxml Sets the script used for generating a PXML file (if none
is available already) to <file>. Please make sure to either
provide a full path or prefix a script in the current folder
with './' so that the script can actually be executed. If
this variable is not specified, $GENPXML_PATH
will be used.
--help / -h Displays this help text.
--icon / -i Sets the icon that will be appended in the pnd to <file>.
--pndname / -p Sets the output filename of the resulting pnd to <file>.
This option is mandatory for the script to function
correctly.
--pxml / -x Sets the PXML file that is to be used to <file>. If you
neither provide a PXML file or set this entry to 'guess',
an existing 'PXML.xml' in your selected '--directory'
will be used, or the script $GENPXML_PATH
will be called to try to generate a basic PXML file for you.
--schema / -s Sets the schema file, that is to be used for validation,
to <file. If this is not defined, the script will try to
use the file '$PXML_schema'. If this fails,
a warning is issued.
If you select the option to create a compressed squashfs, a version >=4.0 of squashfs
is required to be available in your PATH.
