# This script accepts a source file as input on the command line.
|
||
|
|
#
|
||
|
|
# It first loads the 'symbols-in-versions' document and stores a lookup
|
||
|
|
# table for all known symbols for which version they were introduced.
|
||
|
|
#
|
||
|
|
# It then scans the given source file to dig up all symbols starting with CURL.
|
||
|
|
# Finally, it sorts the internal list of found symbols (using the version
|
||
|
|
# number as sort key) and then it outputs the most recent version number and
|
||
|
|
# the symbols from that version that are used.
