• kiwix-read: Read ZIM file content

• kiwix-search: Fulltext search in ZIM files

This is an HTTP request parser. It takes chunks of text as received and returns a hint as to what is required, or returns the HTTP::Request when a complete request has been read. HTTP/1.1 chunking is supported.

jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. It is written in portable C. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect.

Siege is a multi-threaded HTTP/FTP load tester and benchmarking utility. It can stress test a single URL with a user defined number of simulated users, or it can read many URLs into memory and stress them simultaneously. The program reports the total number of hits recorded, bytes transferred, response time, concurrency, and return status.

This plugin creates and validates Captcha images for Catalyst.
