The initial release of tiny-initramfs, which already already covers many use cases.
Note: the Github-generated tarballs (the links with "Source code") are not signed and they do not include the ./configure script - so it will be necessary to run ./autogen.sh before using them. Please use the official release tarballs tiny-initramfs-0.1.tar.* instead (the result of make dist), because they are signed and do not require autoconf and automake to be installed.
