2 improve messages printed from arepack.
4 rewrite atool implement extract_archive that is sensitive or not
7 add option to assume format with -F in some situations (like tar.gz)?
8 add option to always assume -e? and add some option for the reverse (-s, --single)
9 assume -e when passing a single directory as argument?
11 change back error messages to:
12 cannot foo `bar': No such file or directory
13 make function to format error message?
15 have autoconf generate files in debian subdir as well?
17 in readconfig, add datatype checking to options (bool/str/int/..)
19 add 'atest': test archive integrity
20 add compression level control arguments: store (0) or 1-9
21 make sure atool has non-zero rc when acat can't find a file (.arc files and possibly other)
23 improve error message when some program doesn't exist (now gets unnecessary lines)
26 arepack to repack archives?
27 arepack existing.tar existing.zip? OK done
28 arepack SOURCE DEST OK done
29 arepack -F DESTFORMAT -e SOURCE1 SOURCE2.. dest format
30 arepack -e FORMAT SOURCE DEST source format? ??
32 arepack -F.tar.bz2 foo.tar.gz would only gunzip then bzip2. tar not involved!
39 does zip treat *?[]\ chars in filenames specially?
41 use "--" with gzip and others?
43 Reasons to rewrite in C:
44 - use manual ZIP code so that we can extract archive with '../foo' files too!
45 tar fails entirely when the archive contains '../xxx' members.
46 - the option --save-outdir in extract-to mode could be implemented
48 - multiple commands per action more easily (same with perl tho)
49 - always identify format using magic values, ignoring extension (fast!)
50 - i18n much easier (and faster)
53 implement list command for single compressed archives? only gzip supports -l
55 apack dummy.tar.gz /etc/hostname
58 Archive is now extracted with file as dummy/etc/hostname
59 Should it be dummy/hostname or etc-1/hostname instead?
62 add support for SEA arc.
63 add support for szip (hard because its interface is different from gzip)
64 make an ACE archive (using winace stuff), test ACE extraction!
65 add support for DEB files
66 list: dpkg-deb -c FILE.deb
67 extract: dpkg-deb -x FILE.deb $outdir/CONTENTS
68 dpkg-deb -e FILE.deb $outdir/DEBIAN
70 Implement 'use_jar_for_zip' - use jar for zip archives (fastjar) - test
71 Rename 'use_zip_for_jar' - use zip for jar archives - test
72 Enable add command for jar archives!
76 make a script to detect system settings and configure atool appropriately
77 Make it possible to send additional arguments to RAR etc. engine configurable via command line?
78 especially adiff diff -ruN (note the N) option

125 how to extract single compressed file
126 * delete original file afterwards
128 * don't extract at all (refuse)
131 * apack: create new archive (refuse if existing exists)
132 * apack -a: add to existing archives (create if necessary)
138 aunpack -X -x [DIR] extract to dir

144 adiff -D -d print difference between two archives
145 afind -F -f find files in archive (emulate find) [?]
147 arepack -R -r extract and pack archives
153 -f -f (classify) like ls
154 -m[TYPE] from all archives, list only files matching (remaining args are matches)
156 prev: als -e *.tar now: als *.tar
157 prev: als foo.tar f* now: als foo.tar -m f*
160 -X DIR where to extract to (otherwise be smart)
161 -m[TYPE] from all archives, extract only files matching (remaining args are matches)
163 apack ARCHIVE FILE1..
164 -a add files if archive already exists (without -a, refuse to overwrite existing)
165 -e all arguments are files (or dirs) to compress individually
166 -F FORMAT force file format
168 -f allow overwriting of archives (clobber). NOTE: for safety, this implies

175 # This document shows how a future rules file format for atool could look. It
176 # was written to outline what was necessary for such a format. It is quite
177 # possible this format will never become a reality due to its complexity.
179 # use ; to separate commands!
181 # rules and configuration files are the same
183 noinclude # don't include default rules/configuration file!

279 better extraction semantics, cleaner code
281 * always use change to directory for extraction, never specify dir on cmd command-line?
282 use ../for instead of absolute dir
283 merges extract-to and extract
285 * core support for multiple commands per mode (think debian)
287 * better control of user arguments to external command (@args)
289 * better solution than multiarchivecmd - cleaned up
291 * more general commands:
294 * more general options
297 * stripext only based on format! (e.g. unpack gz then strip .gz, not .tar.gz)
299 want aunpack -e to be default!
