I have been a Manjaro user for a few years and, this year, I found myself needing to post capital gains on the NYSE for the Brazilian Federal Revenue Service. I saw that there is a multiplatform adapted package from the Government program for this purpose, GCAP RFB. There are information links for installing on Ubuntu & flavours on the internet, but not for Arch.
As it is a very useful program for many users who have recently started investing, I am looking for some content on installing and operating GCAP.
