═══ LA CORRECCIÓN DE FONDO: no es `pack`, son las IMÁGENES ═══
El SDD 19 y el 20 decían «inyectar el texto de la licencia en `hammer pack`, que es aguas
abajo del ArtifactHash y sale gratis». La conclusión sobre el coste era correcta pero el
SITIO estaba mal, y por una razón que sólo se ve leyendo el código: `pack` produce un
`.swm`, que es una RECETA DE TRANSFORMACIÓN sobre fuente pública y por diseño explícito
«NUNCA transporta binarios cocidos»; e `install` REPRODUCE construyendo, con cache-hit del
corpus, en vez de bajar binarios. O sea que **el canal de paquetes de hammer no distribuye
binarios** y la obligación de acompañar-el-binario ahí casi no aplica.
Donde sí aplica, con toda su fuerza, es en la IMAGEN INSTALABLE: su rootfs se puebla con
`hammer install` sobre un prefix y de ahí sale un USB/ISO lleno de binarios que se le da a
alguien. Ése es el punto de entrega. (La obligación del espejo de FUENTES es otra y sigue
entera: las recetas apuntan a URLs de terceros que se caen.)
═══ LO QUE ENTRA ═══
· `scripts/licencias-textos.sh` + `licenses/`: los 44 textos CANÓNICOS de SPDX
(spdx/license-list-data), uno por identificador realmente en uso — la lista se saca de las
recetas, no de un fichero escrito a mano que se desincroniza. 764K.
· `scripts/licencias-rootfs.sh`: escribe /usr/share/licenses/<pkg>/ con el texto de CADA
licencia de la expresión (`Unlicense OR MIT` ⇒ los DOS textos: en un OR el destinatario
elige, y entregar uno solo le quita una opción que el autor le concedió), más un
MANIFEST.tsv. Medido: 1,0 MB para el perfil `cli` de 44 paquetes.
═══ Y SOBRE TODO: ES UN VETO ═══
Sale ≠0 si algún paquete del rootfs no declara licencia. Un informe que no puede bloquear no
cambia lo que ocurre; esto corta el paso. Y se ganó el sueldo al primer intento: reveló que
los perfiles `base` y `cli` —los dos más simples, los que primero se publicarían— llevaban
10 y 12 paquetes con binarios y licencia desconocida. Curados los 10 que se podían afirmar
(doas, iputils, less, mandoc, procps-ng, rsync, strace, sudo, tree, usbutils); ambos perfiles
bajan a 2.
Esos 2 NO se rellenan a propósito, y quedan vetando:
· lsof — licencia propia del proyecto, sin identificador SPDX. Toca `LicenseRef-lsof` con
su texto, que ya viaja en el tarball (la receta instala su COPYING).
· tzdata — dominio público por declaración de sus autores, y SPDX no tiene identificador
para eso (es una AUSENCIA de licencia, no una licencia). Toca
`LicenseRef-PublicDomain` documentado, no forzar uno de la lista.
De paso: normalizado `GPL-3.0+` (sufijo antiguo) a `GPL-3.0-or-later`, misma equivalencia
documentada que la barra de Cargo. Y el caso especial que puse para `Linux-syscall-note`
(«las excepciones viven en exceptions/») era una suposición razonable y FALSA: SPDX las
publica en el mismo `text/`; ese directorio no existe.

ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA. ansi2knr.c is NOT covered by the above copyright and conditions, but instead by the usual distribution terms of the Free Software Foundation; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program generated from the IJG code, this does not limit you more than the foregoing paragraphs do.

The Unix configuration script "configure" was produced with GNU Autoconf. It is copyright by the Free Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess, config.sub, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely distributable.

It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software. (Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely that very many implementations will support it.) So far as we are aware, there are no patent restrictions on the remaining code.

The IJG distribution formerly included code to read and write GIF files. To avoid entanglement with the Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been simplified to produce "uncompressed GIFs". This technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but are readable by all standard GIF decoders.
