What does vim ` char mean?

Question

I am looking around to try and understand a line of code via latest snipMate plugin source.

The statement appears at the autoload section of the plugin

for expr in s:snippet_filenames(scope,escape(a:trigger, "*[]?{}`'$|#%")) for path in g:snipMate.snippet_dirs for file in s:Glob(path, expr) source `=file` <----- endfor endfor endfor

The above code iterates over all files found in the snippet folder and executes the source statement - but what exactly does it do? what does =file means?

soruce? Are you sure that's correct?

@Carpetsmoker: you're correct, just a typo...

See :help `=. Basically, it will evaluate file as a VimL expression, then insert the result into the command line. E.g. echo `="file" . "name"` will expand to echo filename, and will print the value of the variable filename.

In your case, for example, if file is ticks.txt, source `=file` will execute source ticks.txt.
