# Slackware build script for acefile

# Note: the only ACE archives I could actually find in the wild to
# test this with are the Windows and MS-DOS ACE self-extracting exes,
# found here:

# linked to from https://web.archive.org/web/20170619234433fw_/http://www.winace.com/news.html
# https://web.archive.org/web/2005if_/http://www.winace.com:80/files/ace26.exe

# $ file wace269i.exe 
# wace269i.exe: PE32 executable (GUI) Intel 80386, for MS Windows, Petite compressed, ACE self-extracting archive
# $ file ace26.exe
# ace26.exe: MS-DOS executable, LE executable for MS-DOS, PMODE/W DOS extender, UPX compressed, ACE self-extracting archive

# acefile-unace extracts both of the exes just fine.

# Also, I used dosbox to run the ms-dos ace.exe and created an .ace
# archive with 2 small images in it, and it worked fine, too. Although
# only if the files were small (probably a limitation of the shareware
# ms-dos ace). With large files, acefile-unace and regular unace
# both show CRC errors... but sometimes regular unace will segfault
# instead.

# ...it seems to work just fine. As the README says, it's a bit slow to
# extract, but AFAICT the results are correct.
