Give it a path with character to split at and one to join the crumbs with. It will generate a list of links that act as pointers to previous pages on this path.

Example:

breadcrumbs('/path/to/somewhere')

# results in this, newlines added for readability:

<a href="/path">path</a>/
<a href="/path/to">to</a>/
<a href="/path/to/somewhere">somewhere</a>

Optionally a href prefix can be specified which generate link names a above, but with the prefix prepended to the href path.

Example:

breadcrumbs('/path/to/somewhere', '/', '/', '/mycontroller/action')

# results in this, newlines added for readability:

<a href="/mycontroller/action/path">path</a>/
<a href="/mycontroller/action/path/to">to</a>/
