Pelican plugin to Capitalize title

title_capitalize

"""[OVERVIEW] Pelican plugin to replace “-” with a space in the value of the key “title” articles and pages.

[NOTE] Not possible to have expected value of “title” key without plugin:
https://stackoverflow.com/q/64058029/5951529

[REQUIRED] “FILENAME_METADATA: (?P<title>.*)” in Pelican settings;
this is necessary so as not to add the “title” manually in each article and page.
Otherwise error when running “pelican” command on the command line:
“could not find information about 'title'”.
https://docs.getpelican.com/en/latest/content.html#file-metadata

[REQUIRED] Set “PreserveTitle” key with any value in article/page metadata,
if the “Title” key is specified in the metadata
and you don’t want title_capitalize to capitalize title.

[NOTE] I can’t find a solution without an additional “PreserveTitle” key:
