### Snapshot sources and texlive package database
Mirror the current CTAN archive to our mirror(s) and IPFS (URLs in `default.nix`).
See <https://tug.org/texlive/acquire-mirror.html> for instructions.
See https://tug.org/texlive/acquire-mirror.html for instructions.
### Upgrade package information from texlive package database
```
$ curl -L http://mirror.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb.xz \
| xzcat | uniq -u | sed -rn -f ./tl2nix.sed > ./pkgs.nix

curl -L http://mirror.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb.xz \
| xzcat | uniq -u | sed -rn -f ./tl2nix.sed > ./pkgs.nix
```
This will download a current snapshot of the CTAN package database `texlive.tlpdb.xz`

which is a resource-intensive process:
```
```bash
# move fixedHashes away, otherwise build will fail on updated packages
$ mv fixedHashes.nix fixedHashes-old.nix
mv fixedHashes.nix fixedHashes-old.nix
# start with empty fixedHashes
$ echo '{}' > fixedHashes.nix

$ grep -v -F '/nix/store/' fixedHashes-new.nix > fixedHashes.nix
grep -v -F '/nix/store/' fixedHashes-new.nix > fixedHashes.nix
