Contact each compiler vendor to update their text

Here is the list of all Fortran compilers:

For now I just copied the text from their official websites. We should now contact each vendor and see if they would prefer to change the text that appears at the webpage for their compiler. Perhaps they would like to stress that they have free versions for open source, or such.

We should limit the text to 100 words, to be fair to everyone. Currently all the texts at the webpage fit into 100 words and that seems like the right size to give enough background for each compiler but not be too long.

My 2 cents: if the text comes from the vendor, it should be styled as a citation on the website, so as not to look like the website authors "sell" one compiler better than the other :)
