#           cd to target directory, i.e. where the zim notes shall appear (for example          #
#           to ~/.zim). Run                                                                     #

#           follow instructions. When conversed, open zim and add repository (i.e. current dir) #

# Changes:  Fixed a number of issues where the script hanged. Now displays both "Last changed"  #
#           and "Create date" (if these exists) and conversion date. Added a few character subs.#
#           Some clean-up of the code.                                                          #
