+# This script tests: pbmtoepsi pbmtopsg3 pbmtolps psidtopgm pstopnm
+# Also requires: gs pnmtopnm pnmcrop
+
+# This script is for testing alternative (or minor) utilities that
+# read/write Postscript and encapsulated Postscript:
+# pbmtoepsi, pbmtopsg3, pbmtolps and psidtopgm.
+#
+# We keep these tests separate from those for pnmtops and pstopnm
+# which are far more popular.
+#
+# pbmtopsg3 and pbmtolps produce output that require pstopnm for decoding.
+#
+# If ps-roundtrip.test succeeds and this test fails, it is most likely
+# a problem with one of the minor utilities, and vice versa.
