LATEX2ε for class and package writers
我一路看过来的关于LaTeX的电子书，lshort-cn是后补的，昨天在newsmth上置低才看到的……
SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine. Here are some features of SQLite from sqlite.org.
SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine. Features include:
Transactions are atomic, consistent, isolated, and durable (ACID) even after system crashes and power failures.
Zero-configuration - no setup or administration needed.
Implements most of SQL92. (Features not supported)
A complete database is stored in a single disk file.
Database files can be freely shared between machines with different byte orders.
Supports databases up to 2 terabytes (241 bytes) in size.
Sizes of strings and BLOBs limited only by available memory.
Small code footprint: less than 250KiB fully configured or less than 150KiB with optional features omitted.
Faster than popular client/server database engines for most common operations.
Simple, easy to use API.
TCL bindings included. Bindings for many other languages available separately.
Well-commented source code with over 95% test coverage.
Self-contained: no external dependencies.
Sources are in the public domain. Use for any purpose.

在各种常用的工具中，
正则表达式如此的相似却又不同。
下表列出了一些常用的正则表达式，以及其不同之处。
项目总多，遗漏必有不少，请各位看官不吝指出。
以perl的正则为基准，不同的用法以粉红色标出。
