"""The autotools plugin is used for autotools based parts.
Autotools based projects are the ones that have the usual
`./configure && make && make install` instruction set.
The plugin tries to build using ./configure first, if it is not there
it will run ./autogen and if autogen is not there it will run autoreconf.
This plugin uses the common plugin keywords as well as those for "sources".
For more information check the 'plugins' topic for the former and the
'sources' topic for the latter.
In addition, this plugin uses the following plugin-specific keywords:
- configflags:
(list of strings)
configure flags to pass to the build such as those shown by running
'./configure --help'
- install-via:
(enum, 'destdir' or 'prefix')
Whether to install via DESTDIR or by using --prefix (default is
'destdir')
