       poncho_package_create [options] <dependency-file> <<output-path>>

DESCRIPTION

       poncho_package_create is a simple command-line utility that creates a local Conda environment from an in‐
       put JSON dependency file.  The command creates an environment tarball at output-path that can be sent  to
       and run on different machines with the same architecture.

       The  dependency-file  argument  is  the path (relative or absolute) to the a JSON specification file. The
       output-path argument specifies the path for the environment tarball that is created (should  usually  end
       in .tar.gz).

OPTIONS

        --conda-executable=<path>
               Location  of  conda executable to use. If not given, mamba, $CONDA_EXE, conda, and microconda are
              tried, in that order.

        --no-microconda
               Do not try to download microconda if a conda executable is not found.

        -h,--help
                             Show the help message.

EXIT STATUS

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

EXAMPLE

       poncho_package_create dependencies.json example_venv.tar.gz

       This will create an example_venv.tar.gz environment tarball within the current working  directory,  which
       can then be exported to different machines for execution.
