8 # 2003-08-02 first version
9 # 2003-08-03 using mktemp to create temp files, auto-install iselect
10 # 2003-08-04 catch signals so temp files are not left behind, added
11 # enter new search at end of results, autoconfig
12 # 2003-08-06 changed delimiter to \s/ to prevent conflict with e-mails
13 # 2003-08-15 automatically run apt-get update if there is no package list
14 # (e.g. changing apt/sources.list without update), cut lines
15 # to 80 chars before sending to iselect (bug workaround)
16 # 2003-08-31 changed delimiters to {}, q on detail page brings back list of
17 # results, highlighted search word(s) in package details
18 # 2003-09-01 changed script to work with any POSIX complient shell, and not
19 # only bash (thanks to Ulrich Doehner for bug report and
20 # suggestions), added support to use su if sudo is not
21 # installed, fixed search with more than one word (thanks
22 # to Tobias Gruetzmacher who reported this bug)
23 # 2003-09-04 moved do_sudo before first call (fixes bug when trying to
24 # install iselect)
25 4 dpavlin # 2003-10-09 allow multi-selection of packages to view details
26 3 dpavlin # 2003-11-13 fix for RedHat 9.0 mktemp bug suggested by Dobes Vandermeer
27 4 dpavlin # 2004-07-27 allow multi-selection of packages to install
28 9 dpavlin # 2004-12-04 add quick install options
29 # 2004-12-06 fixed multi-word search

31 # I know it's ugly, but it's still faster than aptitude :-)

33 # It will automatically use sudo if installed or require user to enter root
34 # password when needed. It will also install iselect deb package
35 # if it's not already there.
36 #
37 # WARNING: due to iselect limitation, maximum number of results is
38 # 1020 and maximum length of all results is 1048576 bytes
