#&nbsp;config:&nbsp;-<br>
#<br>
#&nbsp;Provides&nbsp;plugin&nbsp;lookup&nbsp;and&nbsp;meta&nbsp;data&nbsp;extraction&nbsp;utility&nbsp;functions.<br>
#&nbsp;It's&nbsp;used&nbsp;to&nbsp;abstract&nbsp;module+option&nbsp;management&nbsp;in&nbsp;applications.<br>
#&nbsp;For&nbsp;consolidating&nbsp;internal&nbsp;use&nbsp;and&nbsp;external/tool&nbsp;accessibility.<br>
#<br>
#&nbsp;The&nbsp;key:value&nbsp;format&nbsp;is&nbsp;language-agnostic.&nbsp;It's&nbsp;basically&nbsp;YAML&nbsp;in<br>
#&nbsp;a&nbsp;topmost&nbsp;script&nbsp;comment.&nbsp;For&nbsp;Python&nbsp;only&nbsp;#&nbsp;hash&nbsp;comments&nbsp;though.<br>
#&nbsp;Uses&nbsp;common&nbsp;field&nbsp;names,&nbsp;a&nbsp;documentation&nbsp;block,&nbsp;and&nbsp;an&nbsp;obvious<br>
#&nbsp;`config:&nbsp;{&nbsp;..&nbsp;}`&nbsp;spec&nbsp;for&nbsp;options&nbsp;and&nbsp;defaults.<br>
#<br>
#&nbsp;It&nbsp;neither&nbsp;imposes&nbsp;a&nbsp;specific&nbsp;module/plugin&nbsp;API,&nbsp;nor&nbsp;config&nbsp;storage,<br>
#&nbsp;and&nbsp;doesn't&nbsp;fixate&nbsp;module&nbsp;loading.&nbsp;It's&nbsp;really&nbsp;just&nbsp;meant&nbsp;to&nbsp;look<br>
#&nbsp;up&nbsp;meta&nbsp;infos.<br>
#&nbsp;This&nbsp;approach&nbsp;avoids&nbsp;in-code&nbsp;values/inspection,&nbsp;externalized&nbsp;meta<br>
#&nbsp;descriptors,&nbsp;and&nbsp;any&nbsp;hodgepodge&nbsp;or&nbsp;premature&nbsp;module&nbsp;loading&nbsp;just&nbsp;to<br>
#&nbsp;uncover&nbsp;module&nbsp;description&nbsp;fields.<br>
#<br>
#&nbsp;<a href="#-plugin_meta">plugin_meta</a>()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Is&nbsp;the&nbsp;primary&nbsp;function&nbsp;to&nbsp;extract&nbsp;a&nbsp;meta&nbsp;dictionary&nbsp;from&nbsp;files.<br>
#&nbsp;&nbsp;It&nbsp;either&nbsp;reads&nbsp;from&nbsp;a&nbsp;given&nbsp;module=&nbsp;name,&nbsp;a&nbsp;literal&nbsp;fn=,&nbsp;or&nbsp;just<br>
#&nbsp;&nbsp;src=&nbsp;code,&nbsp;and&nbsp;as&nbsp;fallback&nbsp;inspects&nbsp;the&nbsp;last&nbsp;stack&nbsp;frame=&nbsp;else.<br>
#<br>
#&nbsp;<a href="#-module_list">module_list</a>()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Returns&nbsp;basenames&nbsp;of&nbsp;available/installed&nbsp;plugins.&nbsp;It&nbsp;uses&nbsp;the<br>
#&nbsp;&nbsp;plugin_base=[]&nbsp;list&nbsp;for&nbsp;module&nbsp;relation.&nbsp;Which&nbsp;needs&nbsp;to&nbsp;be&nbsp;set&nbsp;up<br>
#&nbsp;&nbsp;beforehand,&nbsp;or&nbsp;injected.<br>
#<br>
#&nbsp;<a href="#-add_plugin_defaults">add_plugin_defaults</a>()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Populates&nbsp;a&nbsp;config_options{}&nbsp;and&nbsp;plugin_states{}&nbsp;list.&nbsp;Used&nbsp;for<br>
#&nbsp;&nbsp;initial&nbsp;setup,&nbsp;or&nbsp;when&nbsp;adding&nbsp;new&nbsp;plugins,&nbsp;etc.&nbsp;Both&nbsp;dicts&nbsp;might<br>
#&nbsp;&nbsp;also&nbsp;be&nbsp;ConfigParser&nbsp;stores,&nbsp;or&nbsp;implement&nbsp;magic&nbsp;__set__&nbsp;handling<br>
#&nbsp;&nbsp;to&nbsp;act&nbsp;on&nbsp;state&nbsp;changes.<br>
#<br>
#&nbsp;<a href="#-get_data">get_data</a>()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Is&nbsp;mostly&nbsp;an&nbsp;alias&nbsp;for&nbsp;pkgutil.<a href="#-get_data">get_data</a>().&nbsp;It&nbsp;abstracts&nbsp;the&nbsp;main<br>
#&nbsp;&nbsp;base&nbsp;path,&nbsp;allows&nbsp;PYZ&nbsp;usage,&nbsp;and&nbsp;adds&nbsp;some&nbsp;convenience&nbsp;flags.‾<br>
#&nbsp;&nbsp;It's&nbsp;somewhat&nbsp;off-scope&nbsp;for&nbsp;plugin&nbsp;management,&nbsp;but&nbsp;used&nbsp;internally.<br>
#<br>
#&nbsp;argparse_map()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Converts&nbsp;a&nbsp;list&nbsp;of&nbsp;config:&nbsp;options&nbsp;with&nbsp;arg:&nbsp;attribute&nbsp;for&nbsp;use&nbsp;as<br>
#&nbsp;&nbsp;argparser&nbsp;parameters.<br>
#<br>
#&nbsp;<a href="#dependency">dependency</a>().depends()/.valid()<br>
#&nbsp;‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾<br>
#&nbsp;&nbsp;Probes&nbsp;a&nbsp;new&nbsp;plugins`&nbsp;depends:&nbsp;list&nbsp;against&nbsp;installed&nbsp;base&nbsp;modules.<br>
#&nbsp;&nbsp;Utilizes&nbsp;each&nbsp;version:&nbsp;fields&nbsp;and&nbsp;allows&nbsp;for&nbsp;virtual&nbsp;modules,&nbsp;or<br>
#&nbsp;&nbsp;alternatives&nbsp;and&nbsp;honors&nbsp;alias:&nbsp;names.<br>
#<br>
#<br>
#&nbsp;Generally&nbsp;this&nbsp;scheme&nbsp;concerns&nbsp;itself&nbsp;more&nbsp;with&nbsp;plugin&nbsp;basenames.<br>
#&nbsp;That&nbsp;is:&nbsp;module&nbsp;scripts&nbsp;in&nbsp;a&nbsp;package&nbsp;like&nbsp;`ext.plg1`&nbsp;and&nbsp;`ext.plg2`.<br>
#&nbsp;It&nbsp;can&nbsp;be&nbsp;initialized&nbsp;by&nbsp;injecting&nbsp;the&nbsp;plugin-package&nbsp;basename&nbsp;into<br>
#&nbsp;plugin_base&nbsp;=&nbsp;[].&nbsp;The&nbsp;associated&nbsp;paths&nbsp;will&nbsp;be&nbsp;used&nbsp;for&nbsp;module<br>
#&nbsp;lookup&nbsp;via&nbsp;pkgutil.iter_modules().<br>
#<br>
#&nbsp;And&nbsp;a&nbsp;central&nbsp;module&nbsp;can&nbsp;be&nbsp;extended&nbsp;with&nbsp;new&nbsp;lookup&nbsp;locations&nbsp;best<br>
#&nbsp;by&nbsp;attaching&nbsp;new&nbsp;locations&nbsp;itself&nbsp;via&nbsp;module.__path__&nbsp;+&nbsp;["./local"]<br>
#&nbsp;for&nbsp;example.<br>
#<br>
#&nbsp;Plugin&nbsp;loading&nbsp;thus&nbsp;becomes&nbsp;as&nbsp;simple&nbsp;as&nbsp;__import__("ext.local").<br>
#&nbsp;The&nbsp;attached&nbsp;plugin_state&nbsp;config&nbsp;dictionary&nbsp;in&nbsp;most&nbsp;cases&nbsp;can&nbsp;just<br>
#&nbsp;list&nbsp;module&nbsp;basenames,&nbsp;if&nbsp;there's&nbsp;only&nbsp;one&nbsp;set&nbsp;to&nbsp;manage.</tt></p>
