    "pseudo-filename-completion is supported in some commands.  To use it,\n\
     use a wildcard expression that will match exactly one file.  I.e., if you\n\
     want to fetch obnoxiouslylongfilename.zip, try 'get obn*.zip.'  Note that\n\
     you can't use the cd command with this feature (yet).",

    "You don't need to type the exact site name with open.  If a site is in\n\
     your .ncftprc or the recent-file (.ncrecent), just type a unique\n\
     abbreviation (substring really).   I.e. 'open wuar' if you have the site\n\
     wuarchive.wustl.edu in your rc or recent-file.",

     as '#set local-dir /usr/tmp' to the file, which will be run at startup.",

    "Use the .ncftprc file to set variables at startup and to add sites that \n\
     need init macros.\n\
     Sample .ncftprc:\n\
     #set pager \"less -M\"\n\

     your .ncftprc.  You can then supply '#5' at the prompt, or use 'open #5'\n\
     later.",

    "Sometimes a directory listing is several screens long and you won't\n\
     remember the thing you wanted.  Use the 'predir' command to re-view the\n\
     listing.  The program keeps the copy locally, so you won't have to wait\n\
     for the remote server to re-send it to you.",

    "Use the 'page' (or 'more') command to view a remote file with your pager.",

    "ncftp may be keeping detailed information on everything you transfer.\n\

     escape codes.",

     output of the 'version' command in your message.  An easy way to do that\n\
     is to compose your message, then do a 'ncftp -H >> msg.'",
