 # Terminology
 
-We introduce terms: **actions**, **options**, **expressions**, and **instructions**. Actions are high-level openvdb tools, which each have unique options, e.g. -mesh2ls geo=1 voxel=0.1, where "-mesh2ls" is an action with two options "geo" and "voxel". Expressions are strings of code with one or more low-level instructions in our stack-based programming language (see below). These expressions start with "{" and ends with "}", and ":" is used to separate values and instructions. E.g. {1:2:+} is an expression with two values (1 and 2) and one instruction "+", and it reduces to the string value "3". See section on the "Stack-based string expressions" below for more details.

 Note that **actions** always start with one or more "-" and (except for file names) its associated **options** always contain a "=" and an optional number of leading characters used for identification, e.g. "-erode r=2" is identical to "-erode radius=2.0", but "-erode rr=2" will produce an error since "rr" does not match the first two characters of any option associated with the action "erode".
