+Construct (python library) 
+
+Construct is a powerful declarative parser (and builder) for binary
+data.
+
+The library provides both simple, atomic constructs (such as
+integers of various sizes), as well as composite ones which allow
+you form hierarchical structures of increasing complexity. Construct
+features bit and byte granularity, easy debugging and testing, an
+easy-to-extend subclass system, and lots of primitive constructs to
+make your work easier:
+
+ -Fields: raw bytes or numerical types
+ -Structs and Sequences: combine simpler constructs into more complex
+  ones
+ -Adapters: change how data is represented
+ -Arrays/Ranges: duplicate constructs
+ -Meta-constructs: use the context (history) to compute the size of data
+ -If/Switch: branch the computational path based on the context
+ -On-demand (lazy) parsing: read only what you require
+ -Pointers: jump from here to there in the data stream
+ -Tunneling: prefix data with a byte count or compress it
+
+This is the Python 3 build of Construct.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
