\include
--------
`\include{file}'
The `\include' command is used in conjunction with the
`\includeonly' command for selective inclusion of files. The `file'
argument is the first name of a file, denoting `file.tex'. If `file'
is one the file names in the file list of the `\includeonly' command or
if there is no `\includeonly' command, the `\include' command is
equivalent to
\clearpage \input{file} \clearpage
except that if the file `file.tex' does not exist, then a warning
message rather than an error is produced. If the file is not in the
file list, the `\include' command is equivalent to `\clearpage'.
The `\include' command may not appear in the preamble or in a file
read by another `\include' command.
