+libpostal is written in modern, legible, C99 and uses the following conventions:
 
-- Keep it roughly object-oriented, as allowed by C
-- Confine almost all mallocs to *name*_new and all frees to *name*_destroy
-- Don't write custom hashtables, sorting algorithms, other undergrad CS stuff
-- Use generic containers from klib where possible
-- Take advantage of sparsity in all data structures
-- Use char_array (inspired by [sds](https://github.com/antirez/sds)) when possible instead of C strings.
-- Throughly test for memory leaks before pushing
-- Keep it reasonably cross-platform compatible, particularly for *nix
+- Roughly object-oriented, as much as allowed by C
+- Almost no pointer-based data structures, arrays all the way down
+- Uses dynamic character arrays (inspired by [sds](https://github.com/antirez/sds)) for safer string handling
+- Confines almost all mallocs to *name*_new and all frees to *name*_destroy
+- Efficient existing implementations for simple things like hashtables
+- Generic containers (via [klib](https://github.com/attractivechaos/klib)) whenever possible
+- Data structrues take advantage of sparsity as much as possible
+- Efficient double-array trie implementation for most string dictionaries
