| # USAGE: abi_checks.sh LIBNAME header1 [header2 ...] |
| # |
| # This script creates symbol and signature lists from the provided header |
| # files with the aid of the mksyms.sh and mksigs.pl scripts (saved as |
| # $LIBNAME.exports.check and $LIBNAME.sigatures.check). It then compares |
| # the resulting files with the files $LIBNAME.exports and $LIBNME.signatures |
| # which it expects to find in the current directory. |
