If the first line of an input file is @code{#NO_APP} or if you use the
@samp{-f} option, whitespace and comments are not removed from the input file.
Within an input file, you can ask for whitespace and comment removal in
-specific portions of the by putting a line that says @code{#APP} before the
+specific portions of the file by putting a line that says @code{#APP} before the
text that may contain whitespace or comments, and putting a line that says
-@code{#NO_APP} after this text. This feature is mainly intend to support
+@code{#NO_APP} after this text. This feature is mainly intended to support
@code{asm} statements in compilers whose output is otherwise free of comments
and whitespace.
@cindex line comment character
Anything from a @dfn{line comment} character up to the next newline is
considered a comment and is ignored. The line comment character is target
-specific, and some targets multiple comment characters. Some targets also have
-line comment characters that only work if they are the first character on a
-line. Some targets use a sequence of two characters to introduce a line
-comment. Some targets can also change their line comment characters depending
-upon command-line options that have been used. For more details see the
-@emph{Syntax} section in the documentation for individual targets.

If the line comment character is the hash sign (@samp{#}) then it still has the
