- * Ex version 3 (see exact version in ex_version.c).
- *
- * Mark Horton, UC Berkeley
- * Bill Joy, UC Berkeley
- * November 1979
- *
- * Changes by Gunnar Ritter, Freiburg i. Br., Germany
- * May 2000
- *
- * This file contains most of the declarations common to a large number
- * of routines.  The file ex_vis.h contains declarations
- * which are used only inside the screen editor.
- * The file config.h contains parameters which can be diddled per installation.
- * The file ex_tune.h contains parameters which should be changed by
- * maintainers only.
- *
- * The declarations relating to the argument list, regular expressions,
- * the temporary file data structure used by the editor
- * and the data describing terminals are each fairly substantial and
- * are kept in the files ex_{argv,re,temp,tty}.h which
- * we #include separately.
- *
- * If you are going to dig into ex, you should look at the outline of the
- * distribution of the code into files at the beginning of ex.c and ex_v.c.
- * Code which is similar to that of ed is lightly or undocumented in spots
- * (e.g. the regular expression code).  Newer code (e.g. open and visual)
- * is much more carefully documented, and still rough in spots.
- *
- * Please forward bug reports to
- *
- *	Mark Horton
- *	Computer Science Division, EECS
- *	EVANS HALL
- *	U.C. Berkeley 94704
- *	(415) 642-4948
- *	(415) 642-1024 (dept. office)
- *
- * or to csvax.mark@berkeley on the ARPA-net.  I would particularly like to hear
- * of additional terminal descriptions you add to the termcap data base.

- * The editor does not normally use the standard i/o library.  Because

- * case the editor needs a printf which prints through "putchar" ala the
- * old version 6 printf.  Thus we normally steal a copy of the "printf.c"
- * and "strout" code from the standard i/o library and mung it for our
- * purposes to avoid dragging in the stdio library headers, etc if we
- * are not debugging.  Such a modified printf exists in "printf.c" here.
