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     # 2003-10-09 allow multi-selection of packages to view and install
26     # 2003-11-13 fix for RedHat 9.0 mktemp bug suggested by Dobes Vandermeer
27     #
28     # I know it's ugly, but it's still faster than aptitude :-)
29     #
30     # It will automatically use sudo if installed or require user to enter root
31     # password when needed. It will also install iselect deb package
32     # if it's not already there.
33     #
34     # WARNING: due to iselect limitation, maximum number of results is
35     # 1020 and maximum length of all results is 1048576 bytes
