The pace.vim script offers a means to measure the pace of
typing (in Insert, Replace, & Virtual Replace modes) in
a preselected manner: cumulative, buffer-total, or instance
(dumpable on demand). It provides a tunable policy tool to
inhibit any mode tracing and to control borderline cases
(Ctrl-c exiting, no input). All data collected in a session
may be carried over and re-used.

The bundled demo.vim script parades a specialised variant
of pace.vim in mock-action with a touch of rhyming.

In order to install the project files into a writable user's
Vim directory, either clone this repository and copy all
pace-vim/pace-vim files or fetch the most recent zipped
archive and extract its files.

Since Vim 8, consider assembling a Vim package for either
cloning, copying, or extracting:

:help packages

Having the files installed, launch Vim and list all doc/
locations:

:echo finddir('doc', &runtimepath, -1)

Now generate the help tags:

:helptags /path/to/doc

Then read the documentation:

:help pace.txt
