TIFF Software Distribution
--------------------------
This file is just a placeholder; the entire documentation is now located
as reStructuredText in the doc directory. To view the documentation
as HTML, visit https://libtiff.gitlab.io/libtiff/ or
http://www.simplesystems.org/libtiff/ or within the release package
in the doc/html-prebuilt directory. The manual pages are
located at doc/man-prebuilt.
The release package can be downloaded at
http://download.osgeo.org/libtiff/
If you can't hack either of these options then basically what you
want to do is:
% ./configure
% make
% su
# make install
More information, email contacts, and mailing list information can be
found online at http://www.simplesystems.org/libtiff/
Source code repository

[GitLab issues](https://gitlab.com/libtiff/libtiff/issues)
Previously, the project used
[Bugzilla](http://bugzilla.maptools.org/buglist.cgi?product=libtiff). This
is no longer in use, and all remaining issues have been migrated to GitLab.
