# Test that all available .rc files are merged and overrides are handled.
# The internal .rc is constructed as follows:
#
# 1. Use NCRCENV_RC environment variable exclusively if defined
# 2. If NCRCENV_RC is not defined then merge the set of rc files in this order:
#    1. $RCHOME/.ncrc
#    2. $RCHOME/.daprc
#    3. $RCHOME/.docsrc
#    4. $CWD/.ncrc
#    5. $CWD/.daprc
#    6. $CWD/.docsrc
#    Entries in later files override any of the >earlier >files
# RCHOME overrides HOME when searching for .rc files.

# Since this involves a shared resource: the .rc files in current working directory,
# we need to isolate from any other test.

# Make sure execdir and srcdir absolute paths are available
