Kartik Batch Link Tester (BLT) is a program that helps people who make websites check if all the links on their website work correctly.
Imagine you have a toy box with lots of toys inside. You want to make sure that all your toys are in good condition and none are missing. So, you take out each toy and check if they are in good condition and if they are all there. This is what Kartik BLT does for website links. It takes out each link on the website and checks if they are working properly or not.
When you visit a website, you may see text or pictures that you can click on. These are called links. They take you to another page or another website when you click on them. Sometimes, these links don't work or they take you to the wrong place, and it can be annoying for the person who is trying to use the website.
Kartik BLT helps website makers find these broken or incorrect links so that they can be fixed. This makes the website better for people who use it.
Overall, Kartik BLT is like a helper that makes sure all the links on a website work properly, so that people can easily use the website without any problems.
