It borrows ideas from various makedepend scripts -# and should be compatible with most. -# -# By default we use grep to extract include file names from -# source files. We source an "rc" file '$Mydir/.${Myname}rc' which -# can contain variable assignments such as: -#.nf -# -# cpp_c=/usr/lib/cpp -# cpp_cc=g++ -E -# ... -# -#.fi -# If the variable 'cpp_$suffix' is set, we use it as our cpp in -# place of grep. The program referenced by these variables are -# expected to produce output like: -#.nf -# -# # 10 \"/usr/include/stdio.h\" 1 -# -#.fi -# This allows us to skip most of our processing. For lex,yacc -# and other source files, grep is probably just as quick and -# certainly more portable. -# -# If the "rc" file does not exist, we create it and attempt to -# find cpp or an equivalent cc invocation to assign to 'cpp_c'. -# -# AUTHOR: -# Simon J.
