# # m4 macros from the Unidata netcdf 2.3.2 pl4 distribution. Modified for use
# # with GNU Autoconf 2.1. I renamed these from UC_* to DODS_* so that there
# # will not be confusion when porting future versions of netcdf into the DODS
# # source distribution. Unidata, Inc. wrote the text of these macros and holds
# # a copyright on them.
# #
# # jhrg 3/27/95
# #
# # Added some of my own macros (don't blame Unidata for them!) starting with
# # DODS_PROG_LEX and down in the file. jhrg 2/11/96
# #
# # I've added a table of contents for this file. jhrg 2/2/98

# # 1. Unidata-derived macros.
# # 2. Macros for finding libraries used by the core software.
# # 3. Macros used to test things about the compiler
# # 4. Macros for locating various systems (Matlab, etc.)
