+# Original Author: Ciaran McCreesh <ciaranm@gentoo.org>
+# Maintainers:     Vim Herd <vim@gentoo.org>
+# Purpose:         Simplify installing spell files for vim7
+#
+
+# How to make a vim spell file package using prebuilt spell lists
+# from upstream (${CODE} is the language's two letter code):
+#
+# * Get the ${CODE}.*.spl and README_${CODE}.txt files. Currently they're
+#   at ftp://ftp.vim.org/pub/vim/unstable/runtime/spell/ .
+#
+# * Stick them in vim-spell-${CODE}-$(date --iso | tr -d - ).tar.bz2 . Make sure
+#   that they're in the appropriately named subdirectory to avoid having to mess
+#   with S=.
+#
+# * Upload the tarball to the Gentoo mirrors.
+#
+# * (for now) Add your spell file to package.mask next to the other vim7
+#   things. The vim herd will handle unmasking your spell packages when vim7
+#   comes out of package.mask.
+#
+# * Create the app-vim/vim-spell-${CODE} package. A sample ebuild will look
+#   something like (header removed):
+#
+#     VIM_SPELL_LANGUAGE="French"
+#
+#     inherit vim-spell
+#
+#     LICENSE="GPL-2"
+#     KEYWORDS="~sparc ~mips"
+#     IUSE=""
+#
+# * Don't forget metadata.xml. You should list vim as the herd, and yourself
+#   as the maintainer (there is no need to join the vim herd just for spell
+#   files):
+#
+#     <?xml version="1.0" encoding="UTF-8"?>
+#     <!DOCTYPE pkgmetadata SYSTEM "http://www.gentoo.org/dtd/metadata.dtd">
+#     <pkgmetadata>
+#      <herd>vim</herd>
+#      <maintainer>
+#              <email>your-name@gentoo.org</email>
+#      </maintainer>
+#      <longdescription lang="en">
+#              Vim spell files for French (fr). Supported character sets are
+#              UTF-8 and latin1.
+#      </longdescription>
+#     </pkgmetadata>
+#
+# * Send an email to vim@gentoo.org to let us know.
+#
+# Don't forget to update your package as necessary.
+#
+# If there isn't an upstream-provided pregenerated spell file for your language
+# yet, read :help spell.txt from inside vim7 for instructions on how to create
+# spell files. It's best to let upstream know if you've generated spell files
+# for another language rather than keeping them Gentoo-specific.
