Source code for pygmt

# pylint: disable=missing-docstring
# The main API for PyGMT.
# All of PyGMT is operated on a "modern mode session" (new to GMT6). When you
# import the pygmt library, a new session will be started automatically. The
# session will be closed when the current Python process terminates. Thus, the
# Python API does not expose the `gmt begin` and `gmt end` commands.
