-+p2c for Debian
-+--------------
-+
-+You should be aware that p2c is not perfect in converting Pascal sources
-+to C, and it won't make the best C code.
-+
-+Also if you notice that your translated C program won't compile because
-+of an undefined reference to PASCAL_MAIN function, just comment that line
-+from the C file and it should work.
-+
-+Here are some words from src/INSTALL file that could be of some use:
-+
-++++
-+
-+ Incomplete interface texts for standard Turbo units are included in
-+ turbo.imp. Turbo users will have to flesh these out and write emulations
-+ for whatever parts of the Turbo runtime library they need.
-+
-+ If you wish to edit various system-wide configuration parameters, it is
-+ better to put them in loc.p2crc than in sys.p2crc. As an example, on a
-+ Turbo-oriented environment you may wish to add
-+
-+ Language Turbo
-+
-+ to the loc.p2crc file to replace the normal default (HP Pascal).
-+
-+ PORTABILITY
-+
-+ P2c was originally developed on a homebrew C compiler on the HP Pascal
-+ Workstation operating system. Current development takes place on HP-UX,
-+ which is System V based. The translator has also been compiled and used
-+ on Sun-3's, so presumably it is fairly portable among 32-bit Unix machines.
-+
-+ Many parts of the code will have to be adjusted in order for p2c to work
-+ on a machine with 16-bit ints. I have never had reason or opportunity to
-+ track these down since I don't have access to such a machine. Please note
-+ that code _generated_ by p2c works with either size of int even though p2c
-+ itself does not.
-+
-+ If your compiler supports ANSI prototypes, most of the 16-bit portability
-+ problems will go away except for possible %d/%ld sloppiness in sprintf control
-+ strings. There may be places where p2c tries to cast a pointer into an
-+ int, but I believe all such cases use longs consistently. You will have
-+ a problem if your long type is not large enough to store a pointer.
-+
-+ Because p2c was developed to run under Unix, it is sloppy about memory
-+ allocation. Some data structures are allocated but never freed. Profiles
-+ show that the waste is not too great in most cases, but if it is a problem
-+ you may have to write a garbage collector (this shouldn't be too hard if you
-+ only run the collector after translating each procedure).
-+
-++++

-+Suggests: gcc, gpc
-+Description: Pascal to C translator
-+ P2c is a tool for translating Pascal programs into C. The input
-+ consists of a set of source files in any of the following Pascal
-+ dialects: HP Pascal, Turbo/UCSD Pascal, DEC VAX Pascal, Oregon Software
-+ Pascal/2, Macintosh Programmer's Workshop Pascal, Sun/Berkeley Pascal,
-+ Texas Instruments Pascal, Apollo Domain Pascal. Modula-2 syntax is also
-+ supported.
-+ .
-+ Output is a set of .c and .h files that comprise an equivalent program
-+ in any of several dialects of C. Output code may be kept machine and
-+ dialect-independent, or it may be targeted to a specific machine and
-+ compiler. Most reasonable Pascal programs are converted into fully
-+ functional C which will compile and run with no further modifications,
-+ although p2c sometimes chooses to generate readable code at the expense
-+ of absolute generality.
