A LaTeX command begins with the command name, which consists of a \
followed by either (a) a string of letters or (b) a single non-letter.
Arguments contained in square brackets [] are optional while arguments
contained in braces {} are required.
NOTE: LaTeX is case sensitive. Enter all commands in lower case
unless explicitly directed to do otherwise.
LaTeX environments are created by
\begin{environment} ... \end{environment}
Declarations can be effected by an
environment of the same name.
