Template:Template link expanded with bold

Explanation
This template is a copy of tlb except that it uses a non-proportional, monospaced font instead of normal text:

I.e., it's a tl-style template-link tag that boldfaces the template name, and accepts parameters. Its main use is in distinguishing between multiple templates with similar names, in documentation, talk page discussions, etc.

The rest of the documentation is for tlx, which works the same way (although it doesn't currently behave sanely when no parameters are given; use tlu instead).
