# aspell 0.60.3 and the en dictionaries, built to match what the card already has.
#
# meta-psion.oe lists aspell-en in psion-apps, so every soho image had
# spellchecking. It was the one real gap against Psion's manifest.
#
# WHY 0.60.3 AND NOT PSION'S PINNED 0.50.5.
# The card already carries aspell 0.60.3 runtime -- libaspell.so.15.1.2 and a
# /usr/lib/aspell-0.60/ filter set -- pulled in for balsa and enchant, and balsa
# links libaspell.so.15 directly. A 0.50 dictionary is format-incompatible with a
# 0.60 runtime, and swapping the library out would risk balsa. So the dictionary
# has to match the runtime that is actually there. Deliberate deviation, recorded.
#
# WHY BUILD AT ALL, RATHER THAN SHIP DEBIAN'S DICTIONARY.
# Debian's aspell-en ships the .rws files as symlinks into /var/lib/aspell and
# builds them in postinst. On this machine /var is a tmpfs, so those would vanish
# on every boot. The .rws are built here and installed as REAL files instead.
# Debian's aspell binary is no use either: it wants __gnu_cxx::__pool symbols from
# libstdc++ 4.1 and the card has 6.0.3, gcc 3.4's -- the same constraint that has
# governed every build in this project.
