I'm pretty sure that megatron (the evil file transformer, part of
netatalk) and its permutations should work for going from things like
AppleSingle to AppleDouble.

NAME
megatron, unhex, unbin, unsingle, hqx2bin, single2bin, mac-
binary - Macintosh file format transformer

SYNOPSIS
megatron [ sourcefile... ]

unbin [ sourcefile... ]

unhex [ sourcefile... ]

unsingle [ sourcefile... ]

hqx2bin [ sourcefile... ]

single2bin [ sourcefile... ]

macbinary [ sourcefile... ]

DESCRIPTION
     megatron is used to transform files from BinHex, MacBinary,
     AppleSingle, or netatalk style AppleDouble formats into Mac-
     Binary or netatalk style AppleDouble formats. The netatalk
     style AppleDouble format is the file format used by afpd,
     the netatalk Apple Filing Protocol (AppleShare) server.
     BinHex, MacBinary, and AppleSingle are commonly used formats
     for transferring Macintosh files between machines via email
     or file transfer protocols. megatron uses its name to
     determine what type of tranformation is being asked of it.

     If megatron is called as unhex, unbin, or unsingle, it tries
     to convert file(s) from BinHex, MacBinary, or AppleSingle
     into AppleDouble format. BinHex is the format most often
     used to send Macintosh files by e-mail. Usually these files
     have an extension of ".hqx". MacBinary is the format most
     often used by terminal emulators "on the fly" when transfer-
     ring Macintosh files in binary mode. MacBinary files often
     have an extension of ".bin". Some Macintosh LAN-based email
     packages use uuencoded AppleSingle format to "attach" or
     "enclose" files in email. AppleSingle files don't have a
     standard filename extension.

     If megatron is called as hqx2bin, single2bin, or macbinary,
     it will try to convert the file(s) from BinHex, AppleSingle,
     or AppleDouble into MacBinary. This last translation may be
     useful in moving Macintosh files from your afpd server to
     some other machine when you can't copy them from the server
     using a Macintosh for some reason.

If megatron is called with any other name, it uses the
default translation, namely unhex.

     If no source file is given, or if sourcefile is `-', and if
     the conversion is from a BinHex or MacBinary file, megatron
     will read from standard input.

     The filename used to store any output file is the filename
     that is encoded in the source file. MacBinary files are
     created with a ".bin" extension. In the case of conflicts,
     the old file is overwritten!
