 This command will include 'file' as if it was part of the original script. Note that if a file is included in another directory, the current directory is still where the script was compiled from (not where the included file resides). If the compiler can't find the file it will look for it in every include directory. See \R{addincludedir}{!addincludedir} for more information. If the /nonfatal switch is used and no files are found, a warning will be issued instead of an error. /charset can be used to specify a codepage for plain text files without a BOM.
