# This script searches for technology directories and project directories.
# It sets variables associated with each directory for other scripts to
# use.
#
# The directory hierarchy is expected to be set up as follows:
#
# <project> ----> source/
# ----> synthesis/
# ----> layout/
# ----> tech/<techname> (optional)
#
# "tech" is optional if the technology is in the qflow install location,
# QFLOW_TECH_DIR/<techname>
#
# Optionally, techfiles may be in subdirectory <techname> without the
# intervening "tech" directory. i.e.,
#
# <project> ----> <techname>
#
# Optionally, "tech" may point directly to the directory containing techfile
# data, i.e.,
#
# <project> ----> tech/
#
# If <project> is not specified on the command line, then it is assumed
# to be the current working directory. If any standard subdirectories
# "source", "synthesis", or "layout" are not found, they will be set to
# the project directory. The techfile directory must be found, or
# synthesis cannot proceed.
#
# Source this file using "source" to add variables to the existing shell
# environment.
#
#-------------------------------------------------------------------------
# Environment variables override everything else:
# QFLOW_TECH_DIR path to technology directory
# QFLOW_TECH name of technology
# QFLOW_PROJECT_ROOT path to project top level directory
#
# The second two are checked before calling this routine so
# that there are known values for the two arguments passed
# to it.
