Regular Expressions
===================

   The parser `ebrowse' normally writes regular expressions to its
output file that help the Lisp part of Ebrowse to find functions,
variables etc. in their source files.

   You can instruct `ebrowse' to omit these regular expressions by
calling it with the command line switch `--no-regexps'.

   When you do this, the Lisp part of Ebrowse tries to guess, from
member or class names, suitable regular expressions to locate that
class or member in source files.  This works fine in most cases, but the
automatic generation of regular expressions can be too weak if unusual
coding styles are used.

`--no-regexps'
     This option turns off regular expression recording.

`--min-regexp-length=N'
     The number N following this option specifies the minimum length of
     the regular expressions recorded to match class and member
     declarations and definitions.  The default value is set at
     compilation time of `ebrowse'.

     The smaller the minimum length, the higher the probability that
     Ebrowse will find a wrong match.  The larger the value, the larger
     the output file and therefore the memory consumption once the file
     is read from Emacs.

`--max-regexp-length=N'
     The number following this option specifies the maximum length of
     the regular expressions used to match class and member
     declarations and definitions.  The default value is set at
     compilation time of `ebrowse'.

     The larger the maximum length, the higher the probability that the
     browser will find a correct match, but the larger the value the
     larger the output file and therefore the memory consumption once
     the data is read.  As a second effect, the larger the regular
     expression, the higher the probability that it will no longer
     match after editing the file.
