.Ss Comments

Anything following a

.Sq \e"

delimiter is considered a comment (unless the

.Sq \e

itself has been escaped) and is ignored to the end of line.

Furthermore, a macro line with only a control character

.Sq \. ,

optionally followed by whitespace, is ignored.

Unless specifically escaped, consecutive blocks of whitespace are pruned

from input. These are later re-added, if applicable, by a front-end

utility such as

Beyond the

If two consecutive lines exhibit the latter behaviour,

an error is raised. Thus, the following is not acceptable:
