True, but if you have the source file and the unpacked version in the same dir
(the usual case for me) it doesn't work.
Here is an example - jasper-1.900.1.zip is the only file in a dir. I did unzip
jasper*.zip and then
cd jasper-* gave me the following (using set -x):
+ cd jasper-1.900.1 jasper-1.900.1.zip
bash: cd: too many arguments
So I, and probably others too, will have to undefine CD_COMPLAINS in order to
make it work sensibly or use a more complicated method - something like:
SrcName=jasper-
gotoDir=$(zipinfo -1 ${SrcName}*.zip | grep -m1 /)
unzip ${SrcName}*.zip
cd $gotoDir
which is horrible in comparison to using *
jb.

Needless to say, if you originally put zlib in /usr/local or did something else
different, you'll have to adjust those instructions accordingly.
