.h1, .h2, .h3, .h4, .h5, .h6

These directives create level 1--6 headers respectively, that is, markers to delimit the sections of a document to the reader. These headers be numbered and will appear in the table of contents. To create a header which does not appear in the =toc,= the starred variants may be used, that is .h1* in place of .h1 etc.

The header directives take a single argument, the text of the header.

Given the frequency with which headers appear in documents, syntactic sugar is available---any line which starts with between one and six hashes and some space will have the remainder of the line taken as a header, just as in markdown. Hence the line .h3: some text is the same as ### some text. Similarly, .h3*: some other text is the same as ###* some other text.

Example -- Document structure

Sections can be used to break different parts of a document (or in this case presentation script) into smaller marked areas for consumption by an intended audience.

# Introduction
Hello and welcome to our presentation on the dangers of garden gnomes.
# Why Garden Gnomes are Dangerous
You might not know this but garden gnomes are dangerous.
## What a Garden Gnome can do
You never know what a gnome will do when your back is turned.
## What Have Garden Gnomes Been Observed Doing?
Nobody has been able to record any suspicious activity in relation to garden gnomes, but that's exactly what they'd want.
# Conclusion
Watch your back out there, kiddos.

Example -- Document sections (exhaustive document)

The following is an exhaustive list of available headers and their related syntactic sugars.

.h1: This is the largest header
.h2: This is a sub-header
.h3: This is a sub-sub-header
.h4: This header is even deeper
.h5: This is an extremely deep header
.h6: This header is so deep its utility is questionable but here it is

# This is the largest header
## This is a sub-header
### This is a sub-sub-header
#### This header is even deeper
##### This is an extremely deep header
###### This header is so deep its utility is questionable but here it is

.h1*: This appears the same as `.h1` but is un-numbered and absent from the TOC
.h2*: Same as the above but smaller
.h3*: Same as the above but smaller
.h4*: Same as the above but smaller
.h5*: Same as the above but smaller
.h6*: Same as the above but smaller

#* This appears the same as `.h1` but is un-numbered and absent from the TOC

###* Same as the above but smaller
####* Same as the above but smaller
