What is wcurl
?

command, specifically designed for efficient file downloads. It eliminates the need for complex curl

Why Use wcurl
?
The inspiration for wcurl
came from Samuel Henrique's personal experience. Even as a Debian curl
maintainer, he found himself struggling to remember the precise curl
parameters for his preferred download settings. This led to the development of a simpler alternative.
The project was initially presented at the curl-up
conference and received enthusiastic community support, leading to its collaborative development within the Debian community, involving contributions from Sergio Durigan Junior, Guilherme Puida Moreira, and Carlos Henrique Lima Melara.
