NAME

7
8       This is the documentation of spectrographic.

10       NOTE:
11          This is the main page of your project's Sphinx documentation.  It is
12          formatted in reStructuredText.  Add  additional  pages  by  creating
13          rst-files  in  docs  and adding them to the toctree below.  Use then
14          references in order to link them from this page, e.g.   Contributors
15          and Changelog.
16
17          It  is  also  possible to refer to the documentation of other Python
18          packages with the Python domain syntax. By default you can reference
19          the  documentation  of  Sphinx,  Python,  NumPy,  SciPy, matplotlib,
20          Pandas, Scikit-Learn. You can  add  more  by  extending  the  inter‐
21          sphinx_mapping in your Sphinx's conf.py.
22
23          The pretty useful extension autodoc is activated by default and lets
24          you include documentation from docstrings. Docstrings can be written
25          in Google style (recommended!), NumPy style and classical style.

215   spectrographic.cli module
216       This is a skeleton file that can serve as a starting point for a Python
217       console script. To run this script uncomment the following lines in the
218       [options.entry_points] section in setup.cfg:
219
220          console_scripts =
221                 spectrographic = spectrographic.cli:run
222
223       Then run python setup.py install which will install the  command  spec‐
224       trographic inside your current environment.
225
226       spectrographic.cli.main(args)
227              Main entry point allowing external calls
228
229              Parameters
230                     args ([str]) -- command line parameter list
231
232       spectrographic.cli.parse_args(args)
233              Parse command line parameters
234
235              Parameters
236                     args  ([str])  --  command  line  parameters  as  list of
