# Notes about interpretation of tests:
# The test file was generated in the compilation of axodraw2's manual,
# and this test script therefore verifies much functionality of
# axohelp. However, if the test fails, it may not actually indicate
# an error. There are two possibilities for spurious failure:
# a. There is a mismatch of line endings (\n v. \r\n, etc) between the
# generated test file test-big.ax2 and the reference file
# test-big.ax2-std. Correct the problem by adjusting
# test-big.ax2-std accordingly.
# b. Some of the numbers in the output file are generated by complex
# floating point computations. Rounding errors can generate small
# differences between the generated file and the reference file.
# This results, for example, from a 32-bit executable compared with
# a 64-bit executable, or from a compilation with different
# compilers and the associated libraries (e.g., VisualStudio
# compared with gcc).
# Interpret the results of the test accordingly.
if test -z "$test_srcdir"; then
# If not set, then we are not running from `make check'.
