Node:Comments, Next:Spacing, Previous:Identifiers, Up:Syntax
A comment is started by # , and continues to the end
of the line. Note that the comment symbol # should be followed by
a space (or other white space), though a letter or number is also OK.
The reason is that # followed by certain special symbols
has special (different) meanings.
For example, #( begins a nested comment,
which extends to the next (unmatched) #).
To include the text in the file named filename, do: #<filename>. (This doesn't work quite right.)
