%description
FSL's FIRST subcortical models (336- and 317-vertex sets) and the OMM-1 multimodal
template are 0.3 to 1.1 GB each. Carrying them in a package repository would multiply
that by every chroot and rehost data FMRIB already publishes, so instead this tool
downloads the original archive from FMRIB's public conda channel, checks its sha256
against a manifest shipped here, unpacks only the data/ tree under /var/lib/fsl-data
and links it into /usr/lib/fsl/data where FSL looks.

* Wed Oct 07 2026 Morgan Hough <morgan.hough@gmail.com> - 1.0-1
- Initial package: fsl-data-install and a manifest of FMRIB's large data sets
  (FIRST models 336 and 317, OMM-1), fetched on demand and sha256-verified, so the
  repository does not carry or rehost them. tests/fsl-data-fetch.bats (12 tests,
  three mutation-checked).
