# We first start by creating a way of escaping the characters that have special
# meaning for html, while making sure we don't end up double-escaping at any
# point. The easiest way to do this is to create an S3 class that allows us to
# distinguish between regular text (that needs escaping) and html (that
# doesn't).
#
# We then write an escape method that leaves html unchanged and escapes the
# special characters (&, <, >) in ordinary text. We also add a method for lists
# for convenience

MySQL to Sqlite converter
#!/bin/sh
# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
