+" Airline themes are generated based on the following concepts:
+"   * The section of the status line, valid Airline statusline sections are:
+"       * airline_a (left most section)
+"       * airline_b (section just to the right of airline_a)
+"       * airline_c (section just to the right of airline_b)
+"       * airline_x (first section of the right most sections)
+"       * airline_y (section just to the right of airline_x)
+"       * airline_z (right most section)
+"   * The mode of the buffer, as reported by the :mode() function.  Airline 
+"     converts the values reported by mode() to the following:
+"       * normal
+"       * insert
+"       * replace
+"       * visual
+"       * inactive
+"       The last one is actually no real mode as returned by mode(), but used by
+"       airline to style inactive statuslines (e.g. windows, where the cursor
+"       currently does not reside in).
+"   * In addition to each section and mode specified above, airline themes 
+"     can also specify overrides.  Overrides can be provided for the following
+"     scenarios:
+"       * 'modified'
+"       * 'paste'
+"
+" Airline themes are specified as a global viml dictionary using the above
+" sections, modes and overrides as keys to the dictionary.  The name of the
+" dictionary is significant and should be specified as:
+"   * g:airline#themes#<theme_name>#palette
+" where <theme_name> is substituted for the name of the theme.vim file where the
+" theme definition resides.  Airline themes should reside somewhere on the
+" 'runtimepath' where it will be loaded at vim startup, for example:  
+"   * autoload/airline/themes/theme_name.vim
+"
+" For this, the dark.vim, theme, this is defined as
+let g:airline#themes#dark#palette = {}
+
+" Keys in the dictionary are composed of the mode, and if specified the
+" override.  For example:
+"   * g:airline#themes#dark#palette.normal 
+"       * the colors for a statusline while in normal mode
+"   * g:airline#themes#dark#palette.normal_modified 
+"       * the colors for a statusline while in normal mode when the buffer has
+"         been modified
+"   * g:airline#themes#dark#palette.visual 
+"       * the colors for a statusline while in visual mode
+"
+" Values for each dictionary key is an array of color values that should be
+" familiar for colorscheme designers:
+"   * [guifg, guibg, ctermfg, ctermbg, opts]
+" See "help attr-list" for valid values for the "opt" value.
+"
+" Each theme must provide an array of such values for each airline section of
+" the statusline (airline_a through airline_z).  A convenience function, 
+" airline#themes#generate_color_map() exists to mirror airline_a/b/c to
+" airline_x/y/z, respectively.
+
+" The dark.vim theme:
+let s:airline_a_normal   = [ '#00005f' , '#dfff00' , 17  , 190 ]
+let s:airline_b_normal   = [ '#ffffff' , '#444444' , 255 , 238 ]
+let s:airline_c_normal   = [ '#9cffd3' , '#202020' , 85  , 234 ]
+let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(s:airline_a_normal, s:airline_b_normal, s:airline_c_normal)
+
+" It should be noted the above is equivalent to:
+" let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(
+"    \  [ '#00005f' , '#dfff00' , 17  , 190 ],  " section airline_a
+"    \  [ '#ffffff' , '#444444' , 255 , 238 ],  " section airline_b
+"    \  [ '#9cffd3' , '#202020' , 85  , 234 ]   " section airline_c
+"    \)
+"
+" In turn, that is equivalent to:
+" let g:airline#themes#dark#palette.normal = {
+"    \  'airline_a': [ '#00005f' , '#dfff00' , 17  , 190 ],  "section airline_a
+"    \  'airline_b': [ '#ffffff' , '#444444' , 255 , 238 ],  "section airline_b
+"    \  'airline_c': [ '#9cffd3' , '#202020' , 85  , 234 ],  "section airline_c
+"    \  'airline_x': [ '#9cffd3' , '#202020' , 85  , 234 ],  "section airline_x
+"    \  'airline_y': [ '#ffffff' , '#444444' , 255 , 238 ],  "section airline_y
+"    \  'airline_z': [ '#00005f' , '#dfff00' , 17  , 190 ]   "section airline_z
+"    \}
+"
+" airline#themes#generate_color_map() also uses the values provided as
+" parameters to create intermediary groups such as:
+"   airline_a_to_airline_b
+"   airline_b_to_airline_c
+"   etc...
