USAGE = '''
This file greps HTML files for keywords in a context-sensitive manner.
Example:
$ ./tools/html-grep '#group-pms' '.filters'
templates/zerver/right-sidebar.html 45
div.right-sidebar#right-sidebar
div#group-pm-list
ul.filters.scrolling_list#group-pms
Keyword syntax:
When supplying keywords, they must correspond to HTML elements,
classes, or ids. Typical keywords are:
li // search for "<li>"
'.modal' // search for '<foo class="modal">'
'#intro' // search for '<bar id="intro">'
Searches are context-sensitive in the sense that the keyword
may be found among parent tags of a leaf tag, not just the leaf
tag itself. (Think of this as being similar to the way a
browser applies nested CSS styles; it looks at the whole HTML
tree.)
Finding files to search:
The tool currently searches your git repo for files with
the extension .html or .handlebars., and then it does
the grep against all those files.
TODO: allow specific files to be searched.
