This installer is built from Sigil source commit dfe9ed8.
Requires a Linux system with a libc version of 2.19 or higher (ldd --version), and xz-utils (to uncompress the installer archive).
Please note that "self-contained" does not mean portable or relocatable!!
NOTE: Please do not report issues with this Sigil installer in the official Sigil issue tracker. Use this repository's issue system instead instead. Sigil feature requests raised here will also be closed without comment.
If you'd like to verify the gpg sig files for the installers, my GPG fingerprint can be found in the first post at:
