+workoutcard.rb
+==============
+
+This is a tool to generate LaTeX-based workout logging cards. The format in which the exercises are specified can be learned by looking at the examples lower.workout
+and upper.workout.
+
+It is not very well written but does the job well. I only released it, because other people might find it useful and I have no intent to maintain or improve the code.
+
+Example
+-------
+
+1. Specifu your Workout
+
+```
+$ cat lower.workout
+```
+```ruby
+{ :year      => 2014,
+  :title     => "Upper Body Workout",
+  :exercises => [[{ :name => "Bench Press",
+                   :variant => "Dumbbells", 
+                   :sets => 3, :reps => 8 },
+                 { :name => "Seated Rows",
+                   :variant => "Lever",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Fly",
+                   :variant => "Pec Deck",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Cable Pulldown",
+                   :variant => "Close Grip",
+                   :sets => 3, :reps => 8 }],
+                [{ :name => "Military Press",
+                   :variant => "Barbell",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Upright Row",
+                   :variant => "Barbell",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Preacher Curl",
+                   :variant => "EZ-Bar",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Triceps Extension",
+                   :variant => "Dumbbell",
+                   :sets => 3, :reps => 8 },
+                 { :name => "Shrug",
+                   :variant => "Dumbbell",
+                   :sets => 3, :reps => 8 }]] }
+```
+
+2. Build the LaTeX-Source
+
+```
+$ ./workoutcard.rb lower.workout > lower.tex
+```
+
+3. Compile it
+
+```
+$ pdflatex lower.tex
+```
+
+4. Print it
+
+```
+lpr lower.pdf
+```
+
+Dependencies

+
+- Ruby 2.1
+- LaTeX, including packages:
+    - textcomp
