%% Sesame seeds and simit crumbs for LaTeX documents.
%%
%% In the spirit of the `coffee stains' package: makes your manuscript look
%% like it was read by an academic eating a simit (Turkish sesame bagel) over
%% it.  Every shipped page may receive a random, reproducible scatter of
%% oven-roasted sesame seeds and crumbs of crust (caramelised by the pekmez
%% the simit was dipped in before baking); you can also place sprinkles,
%% single seeds and the ring of debris left where a simit was put down.
%%
%% Usage:   \usepackage[<options>]{sesameseeds}
%%
%% Package options / \sesamesetup{<keys>}
%%   mess = none | light | medium | heavy | catastrophic   (default: medium)
%%          (the bare words light, medium, ... also work)
%%   off                  disable everything, hand-placed debris included
%%                        (for the camera-ready version)
%%   seeds = <n>          fixed number of seeds per page (overrides mess)
%%   probability = <0..1> chance that a page gets anything at all (0.8)
%%   randomseed = <int>   change for a different (still reproducible) mess
%%   crumbs = true|false  simit crust crumbs                     (true)
%%   layer = foreground|background  seeds over or under the text (foreground)
%%   firstpage = true|false  allow mess on the first (title) page (true)
%%   size = <factor>      seed size multiplier                   (1)
%%   spread = <length>    size of the fall-out zone              (2.5cm)
%%   stray = <0..1>       fraction of seeds that bounced away    (0.2)
%%   roast = <0..1>       golden (0) to deep-brown (1) roast     (0.5)
%%   black = <0..1>       fraction of black sesame seeds         (0)
%%   crumbratio = <x>     crumbs per seed                        (0.35)
%%   shadow = <0..1>      shadow opacity                         (0.28)
%%
%% Commands (positions are measured from the bottom-left corner of the page;
%% the manual commands use `remember picture', so compile twice):
%%   \sesamesetup{<keys>}
%%   \nosesame                    keep the current page clean
%%   \sesameoff, \sesameon        stop / resume the automatic mess
%%   \sesamesprinkle[<keys>]{<x>}{<y>}  a handful of seeds (keys: count, spread...)
%%   \simitring[<keys>]{<x>}{<y>}       ring of debris where a simit was put down
%%                                      (keys: radius, count, ...)
%%   \sesameseed[<keys>]{<x>}{<y>}      one single seed (keys: angle, roast, size)
