{Doug McKenna}
{\texttt{literac} is a command-line program that converts
source code written in C, \Cplusplus, Objective-C, Swift,
Go, or other languages that use~C-style commenting syntax
(i.e., \texttt{//} and \texttt{/* \dots\ */}) into a \LaTeX\ document.
Computer code is typeset verbatim (with optional line
numbers).  Comments, on the other hand, are stripped of
their delimiters, presented in different styles based on
context, and merged into paragraphs if possible.
A significant amount of attention is paid to ensuring that
\TeX\ does ``the right thing'' in numerous edge cases.
Within comments, a few special commands support common
typesetting tasks, including verbatim and auto-verbatim
code quotes, macros, moving source material forward for
typesetting later in the document, inserting arbitrary \TeX\ code
for math displays, tables, or footnotes, suppressing both code
and comment lines from being typeset, and visual cues for
dividing a large program in one source file into chapters,
sections, subsections, a \texttt{README} file, etc.  This fosters
better documented C code without imposing an intermediate
\texttt{CWEB} (\texttt{CWEAVE}\slash \texttt{CTANGLE}) step on
the source code's developer/tester.  The single implementation
file, \texttt{literac.c}, is documented in the literate style it
implements.  It typesets itself into a 200+ page
document that is its own user manual, its own
implementation, the explanation of the program's
internal design, and an excellent test suite for itself.
Its author built \texttt{literac} to typeset the 90,000+
lines of source code\Dash half of them comments\Dash of
the \texttt{JSBox} library, as commented using
\texttt{literac}'s rules and commands.}
