NAME

       parrot_package_create  -  generate a package based on the accessed files and the preserved
       environment variables

SYNOPSIS

       parrot_package_create [options]

DESCRIPTION

       After recording the accessed files and environment variables of one program with the  help
       of  the  --name-list parameter and the --env-list of parrot_run, parrot_package_create can
       generate a package containing all the accessed files. You can also  add  the  dependencies
       recorded in a new namelist file into an existing package.

OPTIONS

       -a, --add=<path>
              The path of an existing package.

       -e, --env-list=<path>
              The path of the environment variables.

         --new-env
              The relative path of the environment variable file under the package.

       -n, --name-list=<path>
              The path of the namelist list.

       -p, --package-path=<path>
              The path of the package.

       -d, --debug=<flag>
              Enable debugging for this sub-system.

       -o, --debug-file=<file>
              Write  debugging  output  to  this  file.  By  default, debugging is sent to stderr
              (":stderr"). You may specify logs to be sent to stdout (":stdout") instead.

        -h, --help
              Show the help info.

EXIT STATUS

       On success, returns zero. On failure, returns non-zero.

EXAMPLES

       To generate the package corresponding to namelist and envlist:

               % parrot_package_create --name-list namelist --env-list envlist --package-path /tmp/package

       After executing this command, one package with the path of /tmp/package will be generated.

       Here is a short instruction about how to make use of parrot_run, parrot_package_create and
       parrot_package_run  to generate one package for your experiment and repeat your experiment
       within your package.

       Step 1: Run your program under parrot_run and using --name-list and --env-list  parameters
       to record the filename list and environment variables.

               % parrot_run --name-list namelist --env-list envlist /bin/bash

       After  the  execution  of this command, you can run your program inside parrot_run. At the
       end of step 1, one file named namelist containing all the accessed file names and one file
       named  envlist  containing  environment  variables will be generated.  After everything is
       done, exit parrot_run:

               % exit

       Step 2: Using parrot_package_create to generate a package.

               % parrot_package_create --name-list namelist --env-path envlist --package-path /tmp/package

       At the end of step 2, one package with the path of /tmp/package will be generated.

       Step 3: Repeat your program within your package.

               % parrot_package_run --package-path /tmp/package --shell-type bash ...

       After the execution of this command, one shell will be returned, where you can repeat your
       original  program  (Please replace --shell-type parameter with the shell type you actually
       used). After everything is done, exit parrot_package_run:

               % exit

       You can also add the dependencies recorded in a new  namelist  file,  namelist1,  into  an
       existing package:

               % parrot_package_create --name-list namelist1 --env-list envlist1 --new-env envlist1  --add /tmp/package

       After  executing  this  command,  all  the new dependencies mentioned in namelist1 will be
       added into /tmp/package, the new envlist, envlist1, will also be added  into  /tmp/package
       with the name specified by the --new-env option.
