# function my_prefs_edit

# This function should be run to create a .zsh/my_edit_rc file in the user's home
# directory.  This allows the user of my edit and hydra functions to pick their
# own default applications.

# This function is called from edit or nonasciiedit or hydra; there is no
# requirement to run it on its own, but you can.  To reset the defaults, just
# delete the file .zsh/my_edit_rc and then run any of the edit functions

#       my_prefs_edit v 1.1.0 for use INTERACTIVELY with Darwin-OSX ......

#
#       Default values for an ASCII test editor (eg: SubEthaEdit), an image editor
#       (eg: Adobe Photoshop), a postscript display (eg: Preview in 10.3.x works),
#       a PDF display (eg: Preview), and a WYSIWYG HTML editor (eg: Netscape, a
#       free alternative to DreamCrusher), are set using the function
#       my_prefs_edit which is called if the file .zsh/my_edit_rc  does not exist in
#       the user's home directory.  This file can also be edited by hand and is
#       read (and is required) by the functions hydra and nonasciiedit as well.
#
#       The functions hydra and nonasciiedit, as well as my_prefs_edit, are  
#       stand-alone functions and are imported by  edit, which 
#       serves as a wrapper and augments a few features.

#       This function has syntax specific to zsh and will break if you try to
#       use it as an imported function with ksh, sh, bash, etc. so if you use 
#       one of those shells, make edit a zsh shell script and put it into $path.
