+#
+# curl_10char_object_name
+#
+# This shell function accepts a single string argument with unspecified
+# length representing a (*.c) source file name and returns a string which
+# is a transformation of given argument.
+#
+# The intended purpose of this function is to transliterate a (*.c) source
+# file name that may be longer than 10 characters, or not, into a string
+# with at most 10 characters which may be used as an OS/400 object name.
+#
+# This function might not be universally usefull, nor we care about it.
+#
+# It is intended to be used with libcurl's (*.c) source file names, so
+# dependency on libcurl's source file naming scheme is acceptable and
+# good enough for its intended use. Specifically it makes use of the fact
+# that libcurl's (*.c) source file names which may be longer than 10 chars
+# are conformed with underscore '_' separated substrings, or separated by
+# other character which does not belong to the [0-9], [a-z] or [A-Z] sets.
+#
+# This allows repeatable and automatic short object name generation with
+# no need for a hardcoded mapping table.
+#
+# Transformation is done in the following way:
+#
+# 1) Leading directory components are removed.
+# 2) Leftmost dot character and any other char following it are removed.
+# 3) Lowercase characters are transliterated to uppercase.
+# 4) Characters not in [A-Z] or [0-9] are transliterated to underscore '_'.
+# 5) Every sequence of one or more underscores is replaced with a single one.
+# 6) Five leftmost substrings which end in an underscore character are
+# replaced by the first character of each substring, while retaining
+# the rest of the string.
+# 7) Finally the result is truncated to 10 characters.
+#
+# Resulting object name may be shorter than 10 characters.
+#
+# Test case 1221 does unit testng of this function and also verifies
+# that it is possible to generate distinct short object names for all
+# curl and libcurl *.c source file names.
