This option instructs ebrowse to generate a Lisp data base with
name file. By default, the data base is named BROWSE, and
is written in the directory in which ebrowse is invoked.
If you regularly use data base names different from the default, you might want to add this to your init file:
(add-to-list 'auto-mode-alist '(NAME . ebrowse-tree-mode))
where NAME is the Lisp data base name you are using.
By default, each run of ebrowse erases the old contents of the
output file when writing to it. You can instruct ebrowse to
append its output to an existing file produced by ebrowse
with this command line option.
