.SS "PATH AND ENVIRONMENT VARIABLE"
The
.B QccPack
library routines dealing with wavelets searches a number of
directories for filter-bank,
lifting-scheme, and perceptual-weight files.
The order of the directories to be searched for these files is
given by the colon-separated list of directories in the
environment variable
.BR QCCPACK_WAVELET_PATH .
This environment variable is set to a default path by
.BR QccInit (3);
this default path is overridden if the user sets
.B QCCPACK_WAVELET_PATH
prior to invocation of any
.B QccPack
library routines or programs.
The default path is
.B .:$(QCCPACK_INSTALL_DATA_PATH)/Wavelets
where
.B $(QCCPACK_INSTALL_DATA_PATH)
is the installation location of the
.B QccPack
data files (usually /usr/local/share/QccPack).
Note that the current working directory is the first directory in the
default path.
