+ OSSP var - Variable Expansion
+ Version 1.1.3 (02-Oct-2005)
+
+ ABSTRACT
+
+ OSSP var is a flexible, full-featured and fast variable construct
+ expansion library. It supports a configurable variable construct
+ syntax very similar to the style found in many scripting languages
+ (like @name, ${name}, $(name), etc.) and provides both simple scalar
+ (${name}) and array (${name[index]}) expansion, plus optionally one or
+ more post-operations on the expanded value (${name:op:op...}).
+
+ The supported post-operations are length determination, case
+ conversion, defaults, positive and negative alternatives, sub-strings,
+ regular expression based substitutions, character translations, and
+ padding. Additionally, a meta-construct plus arithmetic expressions
+ for index and range calculations allow (even nested) iterations
+ over array variable expansions (..[..${name[#+1]}..]..). The actual
+ variable value lookup is performed through a callback function, so
+ OSSP var can expand arbitrary values.
