This plug-in contains Vim scripts that are used by most of the Vim plug-ins I've written yet don't really belong with any single one of the plug-ins. Basically it's an extended standard library of Vim script functions that I wrote during the development of my Vim profile and plug-ins.
In the past these scripts were bundled with each plug-in, however that turned out to be a maintenance nightmare for me. That's why the miscellaneous scripts are now a proper plug-in with their own page on Vim Online.
For more information about the miscellaneous scripts please refer to the homepage or the project page on GitHub:
Unzip the most recent ZIP archive file (see below) inside your Vim profile directory (usually this is "~/.vim" on UNIX and "%USERPROFILE%\vimfiles" on Windows), restart Vim and execute the command ":helptags ~/.vim/doc" (use ":helptags ~\vimfiles\doc" instead on Windows).
