"""
A tool to automate installation of tool repositories from a Galaxy Tool Shed
into an instance of Galaxy.

Shed-tools has three commands: update, test and install.

Update simply updates all the tools in a Galaxy given connection details on the command line.

Test tests the specified tools in the Galaxy Instance.

Install allows installation of tools in multiple ways.
Galaxy instance details and the installed tools can be provided in one of three
ways:

1. In the YAML format via dedicated files (a sample can be found
   `here <https://github.com/galaxyproject/ansible-galaxy-tools/blob/master/files/tool_list.yaml.sample>`_).
2. On the command line as dedicated script options (see the usage help).
3. As a single composite parameter to the script. The parameter must be a
   single, YAML-formatted string with the keys corresponding to the keys
   available for use in the YAML formatted file (for example:
   `--yaml_tool "{'owner': 'kellrott', 'tool_shed_url':
   'https://testtoolshed.g2.bx.psu.edu', 'tool_panel_section_id':
   'peak_calling', 'name': 'synapse_interface'}"`).

Only one of the methods can be used with each invocation of the script but if
more than one are provided are provided, precedence will correspond to order
of the items in the list above.
When installing tools, Galaxy expects any `tool_panel_section_id` provided when
installing a tool to already exist in the configuration. If the section
does not exist, the tool will be installed outside any section. See
`shed_tool_conf.xml.sample` in this directory for a sample of such file. Before
running this script to install the tools, make sure to place such file into
Galaxy's configuration directory and set Galaxy configuration option
`tool_config_file` to include it.
