Create a FreeBSD pkgng-style package from an arbitrary directory of files.
Based on [bdrewery/freebsd_base_pkgng] (https://github.com/bdrewery/freebsd_base_pkgng)
Provide a manifest_template with the name and particulars of your package, along with a directory path. All files in the directory path provided will be recursively added to the package.
Usage: build-pkg.sh <manifest_template> <files_directory>
Create an example package that will install a file named /usr/local/test/README
./build-pkg.sh manifest_template.example example
The example package can be added with
pkg add my-fortune-20140624.txz
