1.1 root 1: # Makefile for "less"
2: #
3: # Invoked as:
4: # make all
5: # or make install
6: # Plain "make" is equivalent to "make all".
7: #
8: # If you add or delete functions, remake funcs.h by doing:
9: # make newfuncs
10: # This depends on the coding convention of function headers looking like:
11: # " \t public <function-type> \n <function-name> ( ... ) "
12: #
13: # Also provided:
14: # make lint # Runs "lint" on all the sources.
15: # make clean # Removes "less" and the .o files.
16: # make clobber # Pretty much the same as make "clean".
