+   <STRONG>User-Defined</STRONG> <STRONG>Capabilities</STRONG>
+       The preceding section listed the <EM>predefined</EM>  capabilities.
+       They  deal  with  some  special  features for terminals no
+       longer (or possibly never) produced.   Occasionally  there
+       are  special features of newer terminals which are awkward
+       or impossible to represent by reusing the predefined capa-
+       bilities.
+
+       <STRONG>ncurses</STRONG> addresses this limitation by allowing user-defined
+       capabilities.  The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG>
+       option  for  this  purpose.   When  <STRONG>-x</STRONG>  is set, <STRONG>tic</STRONG> treats
+       unknown capabilities as user-defined.   That  is,  if  <STRONG>tic</STRONG>
+       encounters  a capability name which it does not recognize,
+       it infers its type (boolean, number or  string)  from  the
+       syntax and makes an extended table entry for that capabil-
+       ity.  The <STRONG>use_extended_names</STRONG> function makes this  informa-
+       tion conditionally available to applications.  The ncurses
+       library provides the data leaving most of the behavior  to
+       applications:
+
+       <STRONG>o</STRONG>   User-defined capability strings whose name begins with
+           "k" are treated as function keys.
+
+       <STRONG>o</STRONG>   The types (boolean, number, string) determined by  <STRONG>tic</STRONG>
+           can be inferred by successful calls on <STRONG>tigetflag</STRONG>, etc.
+
+       <STRONG>o</STRONG>   If  the  capability name happens to be two characters,
+           the capability is also available through  the  termcap
+           interface.
+
+       While termcap is said to be extensible because it does not
+       use a predefined set of capabilities, in practice  it  has
+       been  limited  to  the  capabilities  defined  by terminfo
+       implementations.  As  a  rule,  user-defined  capabilities
+       intended for use by termcap applications should be limited
+       to booleans and numbers to avoid  running  past  the  1023
+       byte  limit  assumed  by termcap implementations and their
+       applications.  In particular, providing extended  sets  of
+       function  keys  (past the 60 numbered keys and the handful
+       of special named keys) is best done using the longer names
+       available using terminfo.

+       The  <STRONG>ncurses</STRONG> library searches for terminal descriptions in
+       several places.  It uses only the first description found.

+
+           An empty directory name (i.e., if the variable  begins
+           or  ends  with a colon, or contains adacent colons) is
+           interpreted as  the  system  location  <EM>/usr/share/ter-</EM>
+           <EM>minfo</EM>.
 
+       <STRONG>o</STRONG>   Finally, <STRONG>ncurses</STRONG> searches these compiled-in locations:
