Suggestion: user manual build process to include spell check option

hi all,

the following suggestion might be significant or trivial.

the current user manual’s build process does not seem to have a spell check option while building the manual files.
the suggestion here is to incorporate python’s spell checker module to minimize the spelling mistakes that are introduced into the manual.

i would be happy to implement the required changes if anyone is willing to mentor me on how to go about this.
please note i am new to development process / modifying make files of any kind.
