+These are defined by kpathsea; we replace this by the path-searching
+initialisation code taken almost verbatim from comm-w2c.ch.
+@x l.116
+@ We include the additional types |boolean| and |string|. \.{CTIE}
+replaces the complex \.{TIE} character set handling (based on that of
+the original \.{WEB} system) with the standard \.{CWEB} behaviour, and
+so uses the |char| type for input and output.

+@ The \.{ctie} program from the original \.{CTIE} package uses the
+compile-time default directory or the value of the environment
+variable \.{CWEBINPUTS} as an alternative place to be searched for
+files, if they could not be found in the current directory.
+
+This version uses the \Kpathsea/ mechanism for searching files.
+The directories to be searched for come from three sources:
+
+ (a)~a user-set environment variable \.{CWEBINPUTS}
+ (overriden by \.{CWEBINPUTS\_ctie});\par
+ (b)~a line in \Kpathsea/ configuration file \.{texmf.cnf},\hfil\break
+ e.g. \.{CWEBINPUTS=.:$TEXMF/texmf/cweb//}
+ or \.{CWEBINPUTS.ctie=.:$TEXMF/texmf/cweb//};\hangindent=2\parindent\par
+ (c)~compile-time default directories \.{.:$TEXMF/texmf/cweb//}
+ (specified in \.{texmf.in}).
+
+@d kpse_find_cweb(name) kpse_find_file(name, kpse_cweb_format, true)
+
+@ The simple file searching is replaced by the `path searching'
+mechanism that the \Kpathsea/ library provides.
+
+We set |kpse_program_name| to |"ctie"|. This means if the variable
+|CWEBINPUTS.ctie| is present in \.{texmf.cnf} (or |CWEBINPUTS_ctie| in
+the environment) its value will be used as the search path for
+filenames. This allows different flawors of \.{CTIE} to have
+different search paths.
+
+@<Set up |PROGNAME| feature and initialize the search path mechanism@>=
+kpse_set_program_name(argv[0], "ctie");

+@ We include the additional types |boolean| and |string|. \.{CTIE}
+replaces the complex \.{TIE} character set handling (based on that of
+the original \.{WEB} system) with the standard \.{CWEB} behaviour, and
+so uses the |char| type for input and output.
+
+The |kpathsea| library (version 3.4.5) defines the |true|, |false|,
+|boolean| and |string| types in \.{kpathsea/types.h}, so we do not
+actually need to define them here.
+@z
+
+@x l.129 The kpathsea include files find the right header file for these.
+@ We predeclare some standard string-handling functions here instead of
+including their system header files, because the names of the header files
+are not as standard as the names of the functions. (There's confusion
+between \.{<string.h>} and \.{<strings.h>}.)

+@ We don't need to predeclare any string handling functions here, as
+the \.{kpathsea} headers do the right thing.

+The next piece is simplified using the kpathsea kpse_find_file

+@x l.497
+If the environment variable \.{CWEBINPUTS} is set, or if the compiler flag
+of the same name was defined at compile time,
+\.{CWEB} will look for include files in the directory thus named, if
+it cannot find them in the current directory.
