mksrcinfo will include anything the PKGBUILD writes to stdout in the body of the PKGBUILD (i.e. not in any prepare/build/package/etc. functions when being sourced, for example: pkgname=example pkgver=1 echo "Hello world." prepare() {} build() {} package() {} ... which will generate an .SRCINFO file with "Hello world." as the first line. This .SRCINFO file is then not parseable by AUR4 when trying to push it to the package's git repository, which will end up with an error that looks like this: $ git push -u origin master:master Counting objects: 4, done. Delta compression using up to 8 threads. Compressing objects: 100% (4/4), done. Writing objects: 100% (4/4), 4.38 KiB | 0 bytes/s, done.
