Usage: ./package.sh -d DISTRO [OPTIONS]...
Package CloudStack for specific distribution and provided options.

If there's a "branding" string in the POM version (e.g. x.y.z.a-NAME[-SNAPSHOT]), the branding name will
be used in the final generated package like: cloudstack-management-x.y.z.a-NAME.NUMBER.el.x86_64
note that you can override/provide "branding" string with "-b, --brand" flag as well.

Mandatory arguments:
   -d, --distribution string               Build package for specified distribution ("el8")

Optional arguments:
   -p, --pack string                       Define which type of libraries to package ("oss"|"OSS"|"noredist"|"NOREDIST") (default "oss")
                                             - oss|OSS to package with only redistributable libraries
                                             - noredist|NOREDIST to package with non-redistributable libraries
   -r, --release integer                   Set the package release version (default is 1 for normal and prereleases, empty for SNAPSHOT)
   -s, --simulator string                  Build package for Simulator ("default"|"DEFAULT"|"simulator"|"SIMULATOR") (default "default")
   -b, --brand string                      Set branding to be used in package name (it will override any branding string in POM version)
   -T, --use-timestamp                     Use epoch timestamp instead of SNAPSHOT in the package name (if not provided, use "SNAPSHOT")
   -t --templates                          Passes necessary flag to package the required templates. Comma separated string - kvm,xen,vmware,ovm,hyperv

Other arguments:
   -h, --help                              Display this help message and exit

Examples:
   package.sh --distribution el8
   package.sh --distribution el8 --pack oss
   package.sh --distribution el8 --pack noredist
   package.sh --distribution el8 --pack noredist -t "kvm,xen"
   package.sh --distribution el8 --release 42
   package.sh --distribution el8 --pack noredist --release 42
