# Define the package name, source directory, build directory and
# staging directory paths.  Prefixes to directories may be overridden
# by setting shell variables SRC, BUILD and STAGING.  For example,
# doing "export SRC=/root/foo" before calling this script will override
# the default /usr/src and set SRC_DIR to /root/foo/$PKG_NAME instead.

# configuration.

# * Have the finished package reside in /opt/ispell-{version}
# * Configure CFLAGS for an i586 processor.
# Also patch for conflicting getline declarations.
